100% renewable energy for U.S. by 2050

Here’s how to convert everything from air conditioners to trucks 300x170 End-Use U.S. Power Change over Time, in 100% clean and renewable wind, water, and sunlight (WWS) all-sector energy roadmaps for the 50 United States, by Mark Z. Jacobson et al., 27 May 2015 from fossil fuels to 100% renewable sun, wind, and water power by 2050, generating more jobs than would be lost from dirty energy, stopping tens of thousands of premature deaths from pollution, saving about 4% of U.S. GDP, plus saving $3.3 trillion worldwide climate change costs.

That’s 100% as in no coal, oil, natural gas, nuclear, or biomass, just clean solar, wind, and water power: 90% by 2035, 80% by 2030, and 25% by 2025. No new technology required: just existing solar, wind, and water power production with batteries and hydrogen fuel cells for transportation, plus huge efficiency savings both from using electricity directly and through other well-known techniques.

A cleaner, healthier world is within our reach. And when even the country’s most corrupt legislature can unanimously pass and the Georgia governor who took campaign funds from six pipeline companies can sign a solar financing law, while Georgia has already become the fastest-growing solar market in the country, renewable energy is producing the political will to get this done.

Stanford aluminum battery

Another entrant in the battery race to clean energy storage.

Mark Shwartz, Stanford PR, 6 April 2015, Aluminum battery from Stanford offers safe alternative to conventional batteries: The new aluminum-ion battery could replace many of the lithium-ion and alkaline batteries in wide use today.

Stanford University scientists have invented the first high-performance aluminum battery that’s fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many commercial batteries in wide use today.

“We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames,” said Hongjie Dai, a professor of chemistry at Stanford. “Our new battery won’t catch fire, even if you drill through it.”

Although drilling would produce aluminum dust, which isn’t exactly benign. However, point taken.

Personally, I still prefer Continue reading

Tesla opening market for home solar batteries

Elon Musk’s recent reminder that Tesla is working on a house-sized battery has caused quite a stir, but not enough. Tesla alone isn’t the significant part: Tesla opening a market for inexpensive home solar storage methods is. And not all those methods will be batteries: also coming are capacitors, organic vats, compressed air, and water pumped up towers, for storage to car- and house- size to municipal- and utility-scale, all of which will drive solar and wind deployment even faster.

John McDuling, QZ, 30 July 2014, How solar energy storage could make Tesla much more than an automaker,

How lucrative could the solar energy storage business be for Tesla? Almost as lucrative as selling cars.

That’s according to Morgan Stanley, which this week Continue reading

TVA needs to listen to former chair S. David Friedman about solar power

Will you bet on the blinkered money-only policies of the current TVA Chair, or the accurate clean solar future predictions of former TVA Chair S. David Friedman?

Seven years ago S. David Friedman wrote:

“As a substitute for oil, coal, and nuclear energy, the sun can replace the three poisons with inexhaustible fuel.”

The former TVA Chairman wrote that in 2007 his boook Winning Our Energy Independence: An Energy Insider Shows How, which also says (page 4):

There are breakthroughs in new technology that promise to make the cost of solar power as low as that of coal, nuclear, and oil. Almost simultaneously in South Africa and the Silicon Valley in the United States, companies are building huge new solar factories to manufacture a paper-thin solar coating that can generate electricity that could actually lower our electric bills. These breakthroughs promise solar power at 75 percent less than today’s price. Continue reading

Stanford beats Harvard; divests from coal

In the first big win for the fossil fuel divestment campaign, Stanford just did what campaign-founder Harvard has not yet: announced it would divest from coal-mining companies.

Here’s Stanford’s PR dated today, 7 May 2014, Stanford to divest from coal companies,

Acting on a recommendation of Stanford’s Advisory Panel on Investment Responsibility and Licensing, the Board of Trustees announced that Stanford will not make direct investments in coal mining companies. The move reflects the availability of alternate energy sources with lower greenhouse gas emissions than coal.

Who is this Advisory Panel? Continue reading

100% sun, wind, and water can power each U.S. state and the world –Stanford study

We have all the technology right now that we need to power the U.S. state by state and the world with solar, wind, and water power. No burning coal or oil or fracked natural gas and no nukes. No need for any new destructive and hazardous methane pipelines. No waiting for batteries. All we have to do is get on with it.


Stanford University researchers led by civil engineer Mark Jacobson have developed detailed plans for each state in the union that to move to 100 percent wind, water and solar power by 2050 using only technology that’s already available. The plan, presented recently at the AAAS conference in Chicago, also forms the basis for The Solutions Project nonprofit.

“The conclusion is that it’s technically and economically feasible,” Jacobson told Singularity Hub.

The plan doesn’t rely, like many others, on dramatic energy efficiency regimes. Nor does it include biofuels or nuclear power, whose green credentials are the source of much debate.

The proposal is straightforward: eliminate combustion as a source of energy, because it’s dirty and inefficient. All vehicles would be powered by electric batteries or by hydrogen, where the hydrogen is produced through electrolysis rather than natural gas. High-temperature industrial processes would also use electricity or hydrogen combustion.

The rest would simply be a question of allowing existing fossil-fuel plants to age out and using renewable sources to power any new plants that come online….

“The greatest barriers to a conversion are neither technical nor economic. They are social and political,” the AAAS paper concludes.

For Georgia, that’s 40% solar PV plants, 35% offshore wind, 13% rooftop PV (6% residential and 7% commercial), 5% concentrating solar plants, 5% onshore wind, and 1% each wind, tide, and conventional hydro power. Plus 210,200 construction jobs and 101,000 operation jobs. And saving $14.3 billion per year Continue reading

Adding another charter school authorizer reduces academic learning —Karen Noll

Received today on Georgia charter schools do no better than traditional public schools. -jsq

The Stanford study, Multiple Choice: Charter school performance in 16 states (p. 4), also found that multiple authorizers:

Figure 15: Charter School Effect of Policy Variables

States that empower multiple entities to act as charter school authorizers realize significantly lower growth in academic learning in their students, on the order of -.08 standard deviations.

Currently we have the local boards of education that authorize charter schools at a very high rate, 94%. If the charter is not approved by the local board then they can appeal to the Dept of Ed. For approval. So, by adding another authorizer in the form of the UNCONSTITUTIONAL charter school commission you simply reduce the academic learning of the students! This is not about education this amendment is about the money earned by some to keep power! Our constitution states that we have an obligation to provide free quality education to all Georgians. We have no obligation to line the pockets of the rich with our tax dollars!
