Solar prices will drop much further below fossil fuels

High-placed utility executives have told me solar panels can’t get any cheaper. Here’s why economies of scale will continue to drive solar prices down, just like for Henry Ford’s Model T. There’s no excuse for new pipelines or nukes. Let the sun rise!

tl;dr: If current rates of improvement hold, solar will be incredibly cheap by the time it’s a substantial fraction of the world’s electricity supply.

Solar power prices dropping faster than Moore’s Law

More confirmation that solar power is winning so there’s no excuse for any new pipelines.

tl;dr: Moore’s Law is an analogy. As an analogy, it works. And progress is happening far faster than I projected in my ‘solar Moore’s Law’ piece of 2011.]

Citi agrees fixing climate change is profitable

Save more by acting to fix climate change, on similar overall investment for trying to deal with unfixed effects, says Citi Global Perspectives & Solutions (GPS). Save more on similar expense: that’s profiting by fixing climate change. Fastest way to do that with least expense: deny all new pipelines, all LNG export, and end fracking.

Renewable energy world’s second largest source of electricity

Why are we building any new natural gas pipelines when solar and wind have already won the world? Plus solar and wind don’t frack, don’t need any fuel, don’t require eminent domain, and don’t suck up any cooling water.

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.

Georgia #1 in solar jobs and China beats its own emissions pledge

It’s great the three biggest climate change problem countries are finally 300x454 E2 Top 10 Q1 2015, in Clean Energy Works for US: Q1 2015 Jobs Report, by Environmental Entrepeneurs, 30 June 2015 committing to emissions reductions and other substantial changes, although not enough to, you know, stop global warming from getting even worse. Meanwhile, CO2 emissions did not increase from 2013 to 2014, even though the global economy grew, and this was largely because of renewable energy deployment in China. That’s right: China is actually leading the way faster on climate change than it is promising to do. And the old fake excuse that we need fossil fuels for economic growth is busted. Oh, and Georgia is leading the U.S.!

Jimmy Carter’s dream of a solar-powered world is coming true now

U.S. president Jimmy Carter had a dream, 300x300 10360845 897383750328270 6241606373708524983 N, in Work together to turn our vision and dream into a solar reality --Jimmy Carter, by Climate Reality Project, 20 June 1979 thirty six years before Pope Francis spelled out why we all need to escape a dark hot nightmare, and Jimmy Carter’s sunny dream is now coming true.

Today, in directly harnessing the power of the Sun, we’re taking the energy that God gave us, the most renewable energy that we will ever see, and using it to replace our dwindling supplies of fossil fuels.

Shareholders demand Southern Company stop supporting climate change denial 2015-05-27

It’s not just us gnats anymore, Southern Company now has yellowflies giving it the business about converting from fossil fuels to renewable energy. That’s smart business, since SO called out solar power in its own 2014 Annual Report for increased revenues in both 2013 and 2014. Tomorrow at Callaway Gardens, stockholders including me will vote.

Fossil fuel subsidies 6% of world GDP: more than all govt health care spending in world

End fossil fuel subsidies and cut CO2 emissions by 20%, also removing any need for renewable energy subsidies.

Fossil fuels subsidised by $10m a minute, says IMF: ‘Shocking’ revelation finds $5.3tn subsidy estimate for 2015 is greater than the total health spending of all the world’s governments,

300x251 Subsidies as percent of global GDP, in How Large Are Global Energy Subsidies?, by David Coady, Ian Parry, Louis Sears, and Baoping Shang, 1 May 2015 Fossil fuel companies are benefitting from global subsidies of $5.3tn (£3.4tn) a year, equivalent to $10m a minute every day, according to a startling new estimate by the International Monetary Fund.

The IMF calls the revelation “shocking” and says the figure is an “extremely robust” estimate of the true cost of fossil fuels. The $5.3tn subsidy estimated for 2015 is greater than the total health spending of all the world’s governments.

The vast sum is largely due to polluters not paying the costs imposed on governments by the burning of coal, oil and gas. These include Continue reading →

Divest Harvard is winning, and we all will win sun, wind, and water power

Changing the world is hard and takes courage, but that’s why we will win. Bill Sargent had given up on global projects and turned to smaller local problems where it seemed there was a greater change of making a real difference. He wrote for Harvard Heat Week 27 April 2015, Heat Week: Teaching An Old Dog New Tricks,

But then I met Divest Harvard. Here was a group of bright, eager, sleep-deprived young undergraduates and grad students — free of such skepticism and willing to take on both Big Oil and the richest University in the world in one fell swoop.

He listed a number of ways Divest Harvard is winning because they chose the biggest targets under adverse conditions. For example: Continue reading →
