Solar could be as cheap as coal by end of decade
A report from the Chinese government asserts that solar power will be as cheap as coal by 2015. Industry watchers have already predicted that the cost of solar will drop by half by 2020, putting it at parity with coal-fired power. And solar is already competitive on sunny days when utilities pay a premium for "peak" power.

Gas is greener? Smearing renewables over land use exposes ignorance of fossil fuel lovers
Oregon’s solar highway. Photo: Oregon Department of TransportationA recent column in the New York Times suggested that land use is the greatest environmental problem facing new renewable energy. While getting the facts terribly wrong, it opens a door to talk about the advantages of distributed generation rather than large, central-station power generation. A prime example […]

Buy an electric car, get a steep discount on the rooftop solar panels required to charge it
Ford has teamed up with SunPower to offer buyers of its forthcoming Ford Focus Electric a significant discount on SunPower's home solar power systems. This is more than just two companies teaming up to target a demographic likely to want to be interested in both their products: It also makes sense in terms of helping families get off of oil and coal at the same time.

New LCD screens will make your iPhone solar-powered
What if you could simply leave your iPhone face-up on a table or windowsill in order to trickle charge it and extend its battery? And what if the same technology that turned its screen into a photovoltaic panel also made its display significantly more efficient than current displays, leading to substantially increased battery life even if you're trapped inside a cave?

Utilities cash in when you go solar
Net metering offers a lot to utilities and very little to ratepayers and solar array owners.

Record heat, no solar means Texas is paying 40 times more for power
Texas is hotter than balls right now, and it's not just the state's farmers and wildlife that are paying the price for it: Last week, the state set a record for electricity usage that led to its grid operator paying a whopping $3,000/MWh for peak electricity. To give you some perspective on this, $3,000/MWh translates to $3/KWh, or 40 times the $0.08/KWh a resident of that state normally pays for electricity at home.

Concentrated solar power plants are all wet
Concentrating solar has promised big additions to renewable energy production with the additional benefit of energy storage -- but there's a catch.

Solar-powered oil field runs on sunshine, irony
Put on your coal-fired vegan anti-irony helmets, because Oman is building a solar-powered oil field. Not because it will make them feel good or help them tamp down their emissions (I mean, this is oil they're digging up) but because it makes economic sense.

China working on solar yaks
China is going to increase its solar capacity 10-fold in the next five years. Driving this solar great leap forward will be the "feed-in tariff" -- Chinese citizens who install solar panels will be paid 15 cents for every kilowatt-hour they produce. Germany uses the same strategy, and as a result it has more solar power than any other country in the world.
