Solar is the “Fastest Growing Industry in America” and Made Record Cost Reductions in 2010

By Climate Guest Blogger on Sep 16, 2011 at 11:44 am

The U.S. solar industry grew 102% last year and is on track to grow another 100% this year. What other industry doubled its growth during one of the worst economic periods in our history?

The innovation of the Japan wind power should help that industry too. Wind power is more like indirect solar power, since everything is powered by the sun.

that is encouraging, hopefully nonrenewable;e energy might catch up in US.

Is such growth sustainable, are there realistic projections about where solar will be in 10-20 years?

The UK is set to miss climate change targets it is legally bound to meet, according to an independent analysis.

On current trends, solar PV will fall below $1 per watt by 2026.

http://www.futuretim...29.htm#solar-pv

In other words, you could buy a complete rooftop system for about $5,000 (£3,000), and this would last you 20-25 years. You could even sell excess power back to the grid and actually make a profit.

Japan intends to make 100% of new buildings solar powered by 2030.

...which is in turn powered by me.

This is good news. I've always said growth in renewables will be exponential. A sort of Moore's Law (to steal Will's comparison)

Sea ice cover in the Arctic in 2011 has passed its annual minimum, reaching the second-lowest level since satellite records began, US scientists say.

The minimum level of cover is far below the average of 1979-2000.

We'll have to stop Global Warming in the near future otherwise we'll have weird weather all over the world.

I'm reading "The Future History of the Arctic" at the moment and it's fascinating. The Arctic will be of massive geopolitical importance in the coming years, as oil and gas supplies become available for extraction that were previously inaccessible. There's going to be huge conflict over the routes/territories in the region.

Will the Canadians be able to hold onto their claim that the waters between their Arctic islands are internal waters?

I hope so, but I have a soft spot for Canada.

Apparently Denmark is going to try to challenge Russia for the North Pole (the nearest land to the North Pole is an island off Danish Greenland)

Canada vs the world for the Northwest Passage, Denmark vs Russia for the Pole... well... I'm no geopolitical strategist or military general, but I'm pretty sure I can guess who'll win in those fights.

Already starting to happen, what with all the big storms like the tsunamis and hurricanes. Sure, they happen normally, but not at the rate that we've seen them lately. When you have big hurricanes that cause serious damage and flooding, and tsunamis such as the one in China that caused reactor failure, it's hard to say that it hasn't already happened. I've said it before, but I feel we're starting to see a shift in weather patterns due to extreme weather. Areas that are used to cold weather are now getting warmer, and warmer areas are getting colder, etc.

Looks like your prediction that solar power would become affordable in 2010 came true. I have seen a massive explosion of solar panels around where I live in the last 2 years.

The exponential growth of photovoltaic power is remarkably predictable, doubling every two years for the past twenty years. In about 20 years, solar power will be cheap enough to fuel the entire world's energy needs.

Interesting indeed. This seems to be directly at odds with some of the more pessimistic opinions around here about energy fulfilment in the next few decades! It will be interesting to see if the next twenty years mirror the last twenty in terms of this exponential growth.

It's important to remember though that solar is nowhere near as efficient, versatile or energy-dense as fossil fuels. I'm still very skeptical that we'll make it through the energy crisis (though the timeline assumes we will, somehow)...

Well the timeline has too, otherwise it would end in 40 years, and it would suck to read about the fall of mankind.

That was in japan, but I completely agree with you about the weather. Though earthquakes aren't a part of global warming, so....

We got 3 major floods around here last summer, also tornadoes were very rare untill now. And generally spring and fall shrinked so much it pretty much feels like it's only summer and winter each year. It's kinda like in Monty Python :p

We should also have commercially available fusion power in the next couple of decades or so. This number might be wrong because my memory's a little hazy, but I think it would only take 8 gallons of water undergoing nuclear fusion a day to power the current amount of energy the United States uses.
