By David Roberts 10 Apr 2013 grist.org
Solar power and other distributed renewable energy technologies could lay waste to U.S. power utilities and burn the utility business model, which has remained virtually unchanged for a century, to the ground.

That is not wild-eyed hippie talk. It is the assessment of the utilities themselves.
Back in January, the Edison Electric Institute the (typically stodgy and backward-looking) trade group of U.S. investor-owned utilities released a report [PDF] that, as far as I can tell, went almost entirely without notice in the press. Thats a shame. It is one of the most prescient and brutally frank things Ive ever read about the power sector. It is a rare thing to hear an industry tell the tale of its own incipient obsolescence.
Ive been thinking about how to convey to you, normal people with healthy social lives and no time to ponder the byzantine nature of the power industry, just what a big deal the coming changes are. They are nothing short of revolutionary
but rather difficult to explain without jargon.
So, just a bit of background. You probably know that electricity is provided by utilities. Some utilities both generate electricity at power plants and provide it to customers over power lines. They are regulated monopolies, which means they have sole responsibility for providing power in their service areas. Some utilities have gone through deregulation; in that case, power generation is split off into its own business, while the utilitys job is to purchase power on competitive markets and provide it to customers over the grid it manages... >MORE

Germany can Do It, why not here
Germany is the world's top photovoltaics (PV) installer, with a solar PV capacity as of December 2012 of more than 32.3 gigawatts (GW). The German new solar PV installations increased by about 7.6 GW in 2012, and solar PV provided 18 TWh (billion kilowatt-hours) of electricity in 2011, about 3% of total electricity. Some market analysts expect this could reach 25 percent by 2050. Germany has a goal of producing 35% of electricity from renewable sources by 2020 and 100% by 2050.
Large PV power plants in Germany include Senftenberg Solarpark, Finsterwalde Solar Park, Lieberose Photovoltaic Park, Strasskirchen Solar Park, Waldpolenz Solar Park, and Köthen Solar Park....

(64 posts)Solar energy is produced in a giant off-shore nuclear furnace with absolutely no containment structure. Solar energy is, in fact, the ONLY energy source that's 100% imported. It's un-American!
Reason Number Two:
Solar energy is prone to radiation leaks. Even where solar energy plants are running "properly," much of the solar radiation still leaks out all over the place.
Reason Number Three:
Solar energy is communist. It can be made by hippies in their backyard without suitable profit margins for capitalist corporations.
Reason Number Four:
Solar energy violates interstate commerce laws. With all that energy spreading out all OVER the place, it is often transported across state lines without a license. It's UNCONSTITUTIONAL!
Reason Number Five:
Solar energy encourages corruption of youth. Because of the lack of suitable containment, the solar energy spreads out all over, not just in specific locations, resulting in all sorts of dirty, disreputable youth behavior outdoors, without proper supervision. Like roller blading. PROTECT YOUR CHILDREN!
Reason Number Six:
Solar energy causes cancer. Studies have shown that thousands of people have already contracted skin cancer from this dirty, dangerous, hazardous energy source.
Reason Number Seven:
Solar energy causes a dangerous buildup of vitamin D under the skin, undercutting margins for reputable pharmaceutical companies that know how to medicate you much better.
Reason Number Eight:
Solar energy is unreliable. Half the time it doesn't even work. At night millions find themselves walking around in total darkness!
Reason Number Nine:
Solar energy is extremely vulnerable to weather interference. You just can't TRUST it.
Reason Number Ten:
Solar energy is very inefficient. It contains lots of frequencies you can't even see, like infrared. These frequencies heat up the planet too, causing global warming. Fossil fuels contain NO infrared radiation. Coal, for instance, doesn't have light at all. It's jet black in color.
So stick with PROVEN, RELIABLE, SAFE nuclear, coal and oil.

GE's holdings are so diverse that there are thousands of businesses that could plug up what that corporation use to do.
There is nothing particularly special that a corporation does that can't be done by millions of other people. We don't need corporations, they need us.

(2,561 posts)The utilities, coal companies, oil companies, and gas companies are intertwined financially.
They invest in each other and control big blocks of stock in each other through investment firms, hedge funds, and the banking system.
If they abandoned coal for solar power, they would lose big profits on the sale of coal.
Years ago, I came across a large book that listed oil companies in the U.S. Out of curiosity, I skimmed through it, and discovered some interesting facts.
The book listed business data including assets, revenue, and the names of the board of directors and officers.
There were over 200 oil companies listed in this book. The most salient feature was that the same names, or the same family names, appeared over and over again among the Board of Directors and officers of the various firms.
If utility A switched from coal to solar panels, it would cause big profit losses to the "owners" of utility A who also had big investments in coal company B.
There is a financial royalty that controls most of the capital assets on this planet. Their goal is to prevent competition that wpuld affect their profits.
They are greedy and corrupt. They are not stupid.

Add up all the asphalt parking lots surrounding the nations malls, offices and commuter hubs, and theres more than enough blacktop to pave over Connecticut. Envision Solar International hopes to tranform those barren expanses into green-energy oases by erecting forests of solar trees.

(579 posts)The law guaranteed small hydroelectric power generatorsmostly in Bavaria, a politically conservative area I like to think of as the Texas of Germanya market for their electricity. The EEG required utility companies to plug all renewable power producers, down to the smallest rooftop solar panel, into the national grid and buy their power at a fixed, slightly above-market rate that guaranteed a modest return over the long term. The prices were supposed to balance out the hidden costs of conventional power, from pollution to decades of coal subsidies.
Investors began to approach solar and wind power as long-term investments, knowing there was a guaranteed future for renewable energy and a commitment to connecting it to the grid. Paperwork for renewables was streamlineda big move in bureaucracy-loving Germany. The country invested billions in renewables research in the 1990s, and German reunification meant lots of money for energy development projects in the former East.

Just be careful and check out the reviews before signing a contract; there's a lot of fly-by-night operators too.
None of those deals were around when we installed our panels ten years ago; we had to pay cash. The company we used got bought by another company, and I don't know if they are any good. But our solar panels still work, and the sun is never going out of business!

They all have some capabilities in this area right now. But only at a fraction of the level that will be needed once solar and wind become much more common.
But the writings on the wall. Utility companies who maintain the power production focused model of today will find themselves with excess capacity on their hands, while smarter, load balancing focused companies, will become preferred.
Stop investing in new electric plants. Start investing in flywheel, pumped water and heat energy storage.

Thinkingabout
(30,058 posts)Power sources for years. If we had spent the money to equip homes and businesses with solar, wind and water power instead of invading Iraq we would be much further along. We could alter the oil products and be much cleaner in our environment. Most of these sources are God provided and again it would seem the religious right would be on God's side and thanking for the source.
Another issue I have is the electric companies has admitted for years they do not have enough power and have the "brown outs" for years so here is an answer to their limited sources. When storms hit an area we are without power for days. A lot of homes have their own generators but again many are not efficient if they are gas powered. We are at the mercy of electric companies getting power restored.
This is an issue Obama has embraced and therefore fought by GOP. I had a co worker bragging how Solyndra went bankrupt, a loan started in the Bush administration but of course the GOP has been on the fighting side. I told him $850M was a lot less than the $2B a week we spent in Iraq.

(16,993 posts)...nope.
Their CEOs make millions every year. The reason the utilities can afford to pay such huge salaries is because they pass the costs along to customers. No one is worth that much money, no one.
The utilities have had decades to improve their infrastructure, but they say they can't because they're trying to keep costs to customers low. Of course, no problem passing along the costs of executive salaries to customers.
In my experience, state or local agencies that approve rate increases seem to be in the pocket of the utilities they regulate. Where I live now, there is a request from an electric utility to raise rates by 45 percent by 2016. There is also no competition, so if you want electricity you buy it from this one company.
Cut executive salaries, and stop spending hundreds of thousands on ads telling us how wonderful you are. Pass the savings along to customers. Then--and only then--should a case for increases by made.

(39,166 posts)After all, your refrigerator still runs at night. And maybe you watch movies at night on your television. Meanwhile, the utilities have invested a lot of money in the natural gas peaking plants that smooth out the power from your panels (and everyone else's). They've invested that money based on the fact that they'll be able to sell a minimal amount of gas - enough to pay their employees, and their employees' health benefits, etc. while providing 24/7 power.
So when renewables flood the grid with energy, and they do sometimes, those plants don't make a dime - in fact they lose money. I'm not going to back up natural gas or fracking, far from it. But to think your power is "carbon-free" is a joke - you'll be dependent on fossil fuels for the life of your panels.

You're doing much better than most with carbon. But in a post like this where pro-renewables people get intoxicated on a distributed-power high, it's appropriate to point out that 99/100 of people with solar systems still depend on being hooked up to the grid. And in the mad rush to piss on utilties and big corporations, it's also important to point out that a lot of people can't shell out the thousands required for their own array, so their rates go up to compensate.
Maybe the time will come when solar's affordable for everyone, storage is cheap, and sufficient to cover the occasionally weeklong run of cloudiness...but I doubt it. It's certainly not the most efficient, and ironically, owning our own power is another flavor of privatization - a tendency which liberals usually get huffy about.

This paper created a stir when it was released because it had the appearance of presenting a scenario which could be realized. It can't. It's a house of cards, built on top of other similar houses, and the reason can be summed up as follows:
"If 1 was 2, and 2 was 3, and 3 was 4, then then 1 + 2 + 3 = 9."
Some of the many faulty assumptions of the article:
Several studies (reviewed below) have shown that the solar resource, and the wind resource, are each alone sufficient to power all humankind's energy needs.
A true, but specious and useless observation - similar to saying "the output of Niagara Falls would be enough to water crops in all of Africa".
The operating principle of fossil generation is burn when needed, a principle simple enough that it could be followed without computers, digital high-speed communications, or weather forecastingprecisely the conditions when today's electric system was created, early in the 20th century.
This statement reveals the authors' complete ignorance about the complex computer-balancing load requirements required for independent system operators on today's grid.
But, the real grid management problem is not to simulate a single baseload plant by creating constant output; rather, the problem is to meet fluctuating load reliably with fluctuating generation, for an entire grid.
Grid penetration of more than 10% renewables is proving to be a nightmare for maintaining system reliability, and it's estimated that infrastructure improvements will cost Germany 2 trillion to handle it. Again, the authors are unfamiliar with actual operating conditions and are working from entirely hypothetical assumptions.
For scenarios in which backup is used rarely and at moderate fractions of load, load curtailment is probably more sensible than fossil generation.
Load curtailment? That means shutting down power, or rolling blackouts, to manage shortages in generation.
These papers show up occasionally and are greeted with enthusiastic ahs and oohs but like most assessments of renewables they're filled with more optimism than facts. As a false hope they're not only disingenuous but dangerous, because they divert resources from avenues which show much more promise in dealing with climate change.

These authors do seem to be academicians. I don't think it's fair to say they are completely ignorant.
I must thank you for getting me curious about the operation of national grids.
I found an interesting video describing, in layman's terms, the national grid.
http://ed.ted.com/on/x9bcSF2s
This video has Nigel Williams speaking to Robert Llewellyn about how the National Grid works in the U. K.
Nigel Williams gives an interesting explanation of the national grid in the U. K.
He repeatedly referred to flattening the demand curve, to filling the bathtub, to smoothing out the demand for power.
He commented on the expected affect electric cars will have on the national grid.
He spoke of the complexity of the current national grid.
He said, in the video, he considers the national grid smart.
He said the future national grid will be smarter as more renewable energy comes online and more electric cars get power from the national grid.
He said he does ask a load source to curtail power as needed.
He said the flatter the demand curve for electricity the more efficient the electricity supply and the cheaper for consumers. (Please see video starting 5:10)
In the video, Nigel Williams seems to be a fan of power storage to, as he put it, fill the bathtub. Please see the video starting 5:45. I love what he says the guys love the power storage facility. "It's fantastic".
I got the impression power storage would be beneficial for flattening the demand curve even if all power were produced by coal or gas or non-renewable power generation. Is this a fair impression?
Nigel Williams did say, in the video, he curtails renewable power sources as needed which seems to be a big thing for the media when he does it ... but he's says he's always turned down sources in cost order (I'm not summarizing what he said very well. Please see video starting 7:53).
Is it true Nigel Williams is the head of Electricity System Operation at National Grid in the UK?
Nigel Williams does not strike me as being an academician.
Is it fair to say the authors of the article are trying to argue one doesn't need as much power storage if one overbuilds renewable power sources? At least, this is my simple layman's interpretation of the article.

(39,166 posts)at any given time.
I find it helpful to think of electricity flow in terms of water - there are many analogous characteristics. With water in a hose, if the pressure suddenly increases the hose "gives" a little and doesn't blow up. The analogue with electricity is voltage. When the wind picks up suddenly and blows through a wind farm, there's a sudden increase in voltage, or electrical "pressure", that hits the grid. The lines can absorb some extra pressure. But if it gets too great, huge resistors are switched into the transmission lines which soak up this extra power and dump it as heat. That prevents wires from melting, but of course it's wasteful. So the utilities, ISOs (Independent System Operators) and RTOs (Regional Transmission Operators) try to smooth these voltage bumps with natural gas turbines, which unlike coal or nuclear plants can come online or go offline very quickly (in a matter of seconds). It's better than dumping the power as heat, but not much. Firing up the turbines and shutting them down makes them up to 30% less efficient than letting them run all the time.
Storage, on the other hand, with no mechanical parts to set in motion, loses very little efficiency in the smoothing process. By putting it first in the smoothing chain, you can get smooth out all of the sharp spikes, then finish the job with natural gas. It works.
There are significant problems which need to be overcome. Efficient electrical storage is prohibitively expensive. Then there's the complexity of natural inputs like wind and the sun, and the fact that there isn't nearly as much energy in these sources as people tend to think there is (geothermal and hydro are a different story).

(478 posts)I am a fan of renewable energy.
It sounds, to me, like efficient electrical storage, at a reasonable cost, is key.
I didn't realize efficient electrical storage would benefit not only renewable energy, but also coal and oil and gas and any other non-renewable energy sources.
If I may, I found a wiki link talking about grid energy storage.
http://en.wikipedia.org/wiki/Grid_energy_storage
There is much in the wiki to digest.
From the wiki, it seems having a smart grid is an alternative to grid energy storage. It seems to me, having both, having grid energy storage and having a smart grid, would be best in the real world.
It seems our reference to the "smart grid" is not where we are making the grid smarter, but we are making the devices that demand energy from the grid smarter.
This wiki article had a link to another wiki article on Pumped-storage hydroelectricity.
http://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity
I found a site that discusses electricity storage.
http://www.electricitystorage.org/technology/storage_technologies/technology_comparison
Is it fair to suggest, based on a link from this site,
pumped storage is the best, current choice, for electrical storage?
I have an idea we view electric cars as cars with a different source of energy.
Could we, perhaps, also view electric cars as mobile batteries on wheels?
In an ideal world, would you suggest we have renewable energy sources putting power into pumped-storage hydroelectricity, with electric cars acting both as a means of transportation and as a source of power able to feed power back into the grid and act as an emergency backup should there be an interruption in power from the grid?
I actually like the idea homes could have solar panels that charge electric vehicles. Then I would suggest power from electric vehicles could flow back into the grid, on demand, when the grid requests power.
I am becoming a big fan of electric vehicles. Sadly, the initial cost of an electric vehicle is beyond the amount I can afford. I hope, in time, electric vehicles, will become cheaper, with longer ranges, with reasonable recharge times. I guess my hope is we will have wonderful advances in battery technology.
Is this a reasonable picture to paint of a future with renewable resources, with grid storage, with electric vehicles, with smart devices, i.e. having a "smart grid", drawing power from or giving power to the grid?
Thank you for the link to the California site.

(39,166 posts)where Tom Murphy at the University of California San Diego does a much better job than I could at describing why solving only 1% of our storage needs with pumped hydro would be an incredible accomplishment - using real physics and real math.
http://physics.ucsd.edu/do-the-math/2011/11/pump-up-the-storage/
Many well-intentioned renewables advocates are largely math/physics illiterate, and a rudimentary grasp is necessary to put these ideas on a scale and see whether they make any sense at all. Distributed storage among EVs is another idea where when you do the math it's not going to be practical.
So the energy storage issue is a big problem with no clear solution in sight. As many people know around here, I'm a nuclear advocate. It's not because I don't think there are problems with nuclear - there are. With runaway global warming possibly decades away, however, our options are limited. The energy density of nuclear is off the charts - a chunk of uranium the size of a cigarette lighter is enough to provide power for a family of four, for a year. A pellet the size of your fingernail has more energy than a boxcar full of coal. Nuclear electricity combined with electric vehicles could reduce our carbon contribution to the atmosphere by 90%, and without getting too far into the subject of safety, I believe the dangers of nuclear power have been as overestimated as the viability of renewable energy.

(591 posts)Storing electricity is a different problem. We can do it, we went to the moon in 10 years. I think we can do a better job. Our money and scientists have different priorities.
Here's an 18 year old tech solution for heat storage that was applauded by Bill Richardson, ex Energy sec:
In 1995 Solar One was converted into Solar Two, by adding a second ring of 108 larger 95 m² (1,000 ft²) heliostats around the existing Solar One, totaling 1926 heliostats with a total area of 82,750 m² (891,000 ft²). This gave Solar Two the ability to produce 10 megawattsenough to power an estimated 7,500 homes.[1]
Solar Two used molten salt, a combination of 60% sodium nitrate and 40% potassium nitrate, as an energy storage medium instead of oil or water as with Solar One. This helped in energy storage during brief interruptions in sunlight due to clouds.[1] The molten salt also allowed the energy to be stored in large tanks for future use such as night timeSolar Two had sufficient capacity to continue running for up to three hours after the sun had set.
Solar Two was decommissioned in 1999, and was converted by the University of California, Davis, into an Air Cherenkov Telescope in 2001...Solar Two's 3 primary participants were Southern California Edison (SCE), the Los Angeles Department of Water and Power (LADWP), and the U.S. Department of Energy (DOE)."We're proud of Solar Two's success as it marks a significant milestone in the development of large-scale solar energy projects," said then U.S. Energy Secretary Bill Richardson.
"This technology has been successfully demonstrated and is ready for commercialization. From 1994 to 1999, the Solar Two project demonstrated the ability of solar molten salt technology to provide long-term, cost effective thermal energy storage for electricity generation.", Boeing
On November 25, 2009, after 10 years of not producing any energy, the Solar Two tower was demolished[1] The mothballed site was levelled and returned to vacant land by Southern California Edison. All heliostats and other hardware were removed.

That is 18 year old tech. Imagine if a fraction of the cost of the bogus wars was spent on perfecting this heat storage.
What if a trillion dollars was spent on battery technology? Do you think there would be better batteries and perhaps ways of storing the output from PV farms?

(39,166 posts)If our war budgets were spent on energy, we might be able to pull it off. But people generally are only willing to overspend if they see it as addressing an immediate danger. Global warming is not visceral enough for most people to care, so from a practical standpoint that kind of energy budget would never see the light of day.
I believe reliability would still be a serious problem and unacceptable to most people. We take utility power for granted - we flip the switch, the light comes on. That's because the sources of our power are a few large plants which are easily managed. KISS (Keep It Simple, Stupid) is one of the commandments of engineering, and a system relying on thousands of inputs will not be as reliable - it never is.

(23,156 posts)have figured out they could control the entire solar panel part of generating electricity pretty easily. Get their states to pass regulations that the utility company actually owns all solar rights within their service area. The model here is mineral rights. Then, they charge the customers a fee to install the solar panels on the customer's home or building, and sell the electricity thus generated to the customer.
If I can think of that, why can't they?

(14,255 posts)Years ago I said that we would have all solar power now, if only the corporations could figure out how to charge for sunlight.
Hopefully, the times has passed when such a thing could be possible......

(23,156 posts)I live in New Mexico. When you buy land you almost never get the mineral rights with it. Almost invariably someone else owns them, and they can come in any time they want and exercise those rights. Too bad if they have to bulldoze your house to extract whatever minerals at stake. You have absolutely no recourse.
Why the utility companies haven't decided to claim the solar rights in the space directly above people's houses has me slightly mystified. My guess is that they simply haven't thought of it yet. If that happens, what would get interesting is if people who already have solar panels in place get grandfathered in so that they own their own solar rights.

(12,448 posts)People believe they own their homes and I suppose that's all part of the illusion that keeps the game going. Most of them don't own the water rights on their land, either.

(1,406 posts)So one of the most hated industries is crying that their beloved Capitalism is going to devour them because they are not building a better mouse trap. Kind of sucks when some asshole is hoisted on their own petard.
It must be that evil deregulation they all begged for so they could bust the Unions, now it will bust them hopefully. I just hope all of us will have enough money left after they are burned to the ground. You know, because we all saved so much money when our electrical bills were lowered by deregulation.
I smell a too big to fail coming on.

(34,136 posts)I would love to have solar panels on my property, generating energy to go into my electric cooperative's grid. But they do not have the infrastructure to allow me to put energy in, only to take it out.
I also would NOT want to have to maintain and repair solar panels. I WOULD be happy to make a deal with the electric coop to have them install the panels, they maintain them - the same way they currently maintain the power lines - and I pay a monthly fee, hopefully less than I now pay for electricity. So many Americans would not want to have to maintain the panels or a battery array, I think this would be a practical solution for the utility companies.
When we built our house, I looked into photovoltaics. Aside from the initial investment (the estimate I got was $30,000), not being able to sell my surplus to the electric coop, and the maintenance problem all made it impractical. Instead, I put more money (not as much as the solar would have cost) into building a tight, well insulated building envelope which has already paid off and will pay off no matter what kind of energy I use.
From the OP article:
The panels I looked at were estimated to last 30 years and to pay off the initial cost after the first 7-10 years. This is a better investment than the 30 year cost recovery they talk about above!

(249 posts)FYI, if anyone cares I just put 31 PV 255 Siliken panels with Enphase micro inverters on our roof ($35K). My power company Excel Energy paid for half (50%) of the project cost via a program called Solar Rewards. The Federal tax credit covered another 30%. The system net meters (runs backward to the grid) and will pay for itself in ~ 7 years. My 2012 September monthly bill for natural gas and electricity was $1.24 seriously! I live in Minnesota! I say come on in the waters fine. Just be VERY careful about the PV contractor you choose.

(591 posts)Solar power in Germany
Germany is the world's top photovoltaics (PV) installer, with a solar PV capacity as of December 2012 of more than 32.3 gigawatts (GW).[2] [3] The German new solar PV installations increased by about 7.6 GW in 2012, and solar PV provided 18 TWh (billion kilowatt-hours) of electricity in 2011, about 3% of total electricity.[4] Some market analysts expect this could reach 25 percent by 2050.[5] Germany has a goal of producing 35% of electricity from renewable sources by 2020 and 100% by 2050.[6]
Germany set a world record for solar power production with 22 GW produced at midday on Friday 25 and Saturday 26 May 2012. This was a third of peak electricity needs on Friday and almost half on Saturday.[15]
A feed-in tariff is the most effective means of developing solar power.[16] It is the same as a power purchase agreement, but is at a much higher rate. As the industry matures, it is reduced and becomes the same as a power purchase agreement. A feed-in tariff allows investors a guaranteed return on investment - a requirement for development. A primary difference between a tax credit and a feed-in tariff is that the cost is born the year of installation with a tax credit, and is spread out over many years with a feed-in tariff. In both cases the incentive cost is distributed over all consumers. This means that the initial cost is very low for a feed-in tariff and very high for a tax credit. In both cases the learning curve reduces the cost of installation, but is not a large contribution to growth, as grid parity is still always reached

(5,169 posts)Even the bleakest desert has life that will lose its habitat if we built massive solar farms. I like the rooftop solar idea a lot more. Otherwise, you still have the grid to maintain and will be destroying environmentally sensitive areas. We need to QUIT building on undeveloped areas.

Located in the Arizona desert, Palo Verde is the only nuclear generating facility in the world that is not situated adjacent to a large body of above-ground water. The facility evaporates water from the treated sewage of several nearby municipalities to meet its cooling needs.
The facility is on 4,000 acres (1,600 ha) of land and consists of three Combustion Engineering pressurized water reactors, each with an original capacity of 1.27 gigawatts electrical, current (2007) maximum capacity of 1.24 gigawatts electrical,[3] and typical operating capacity 70%95% of this. The plant is a major source of power for Phoenix and Southern California, capable of serving about 4 million people. The plant provides about 35% of the electricity generated in Arizona each year. The plant was fully operational by 1988, taking twelve years to build and costing $5.9 billion,[4] eventually employing 2,386 people.[5] The plant employs 2,055 full-time on-site workers.
The Nuclear plants will take land too. The difference is the Solar plants won't contaminate the soil for 30,000 years.

The patent system that is currently in place will be one obstacle to overcome however due to powerful R&D companies grabbing up all intellectual rights to new innovations.

(1,309 posts)super insulate your home. R-40 in walls, r-50 in ceiling. Put on cool roof or ASV. Triple glazing with low e coating can really cut the heat loss. Tighten the house up and add Heat exchanger as necessary.Go for stand alone power generation- why put up with the 20 percent inverter loss. Buy that electric car so you can store any excess electric there when the time comes. Use daylighting with light shelves etc. Do it right and the future is bright. Do it wrong and they will still own us.
