5 States with Most Solar & Wind Energy Had Smallest Increase in Electricity Prices 2005-2010

This is, clearly, not a definitive analysis showing that renewable energy such as wind and solar lower electricity rates (or make them increase more slowly), but it is a pretty darn good argument in their favor! And it is also a great piece to share with anyone who thinks renewable energy raises the cost of electricity. Add in the health benefits, job creation benefits, grid security benefits, and environmental benefits and my hunch is that any analysis on the matter would tell us, “Hey, it’s about time we put the Big money into renewable energy!” (More on wind costs and solar costs (.. and solar costs) you might want to take a look at.)

Harnessing the Sun's Energy for Water and Space Heating

The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these “solar thermal collectors” use the sun’s energy to heat water, space, or both.

China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors installed by the end of 2010 — nearly two thirds of the world total. This is equivalent to 118,000 thermal megawatts of capacity, enough to supply 112 million Chinese households with hot water. With some 5,000 Chinese companies manufacturing these devices, this relatively simple low-cost technology has leapfrogged into villages that do not yet have electricity. For as little as $200, villagers can install a rooftop solar collector and take their first hot shower. This technology is sweeping China like wildfire, already approaching market saturation in some communities. Beijing’s goal is to reach 300 million square meters of rooftop solar water heating capacity across the country by 2020, a goal it is likely to exceed.

Solar Power Becomes Cheaper Than Diesel Generators in India

While the passage of time makes solar cost competitive for many Americans right now, the question of cost competitiveness is not a simple one for solar. It depends on location, installation costs, and what kind of power solar is competing against. In Africa, solar has already become cheaper than kerosene in many locations. And now Renewable Energy News reports that solar is becoming cheaper than diesel generators in India as French-company Solardirect has bid to supply the energy grid with solar power at a rate cheaper than the average for diesel generators:

Solar feed-in tariffs fall by half

Subsidies for solar panels installed after Monday will fall by as much as 50 per cent from next April, assuming the government adopts proposals set out in the on-going consultation on its popular feed-in tariff scheme.

The consultation on new rates for photovoltaic (PV) systems with capacity of 250kW or below does not conclude until 23 December. But the government’s controversial package of reforms suggest the proposed cuts will come into force for installations completed 12 days prior to the closing date of the consultation exercise.

apple-spaceship

Apple has updated their plans that describe their future headquarters yesterday. The updated Spaceship campus is now planned to include solar panels on its roof, and as ugly as it may have looked through the eyes of Steve Jobs, maybe, the idea is not bad – after all it will generate around 5 megawatts of clean electricity to power the factory where grown-up toys are made.

The Spaceship’s rooftop has been estimated to have around 750,000 square feet. 9to5mac.com, a website specialized in Apple news calculated that about 500,000 sq ft will be used for solar power. Assuming that an average solar panel produces around 10 watts per square foot, that gives the 5 megawatt figure.

Renewable energy investments are surpassing investments in new fossil fuel power for the first time ever, according to Bloomberg New Energy Finance as reported by Joe Romm on ThinkProgress. Adding to the encouraging news, Bloomberg New Energy Finance reported that the trillionth dollarhas been invested in renewable energy, energy efficiency and smart energy technologies.Wind, solar, wave and biomass energy attracted $187 billion of investment capital in 2010 compared to $157 billion for natural gas, oil and coal, according to Bloomberg New Energy Finance’s latest data and calculations. A faster pace of wind and solar power installations, along with oversupply in various wind and solar power plant inputs, is driving installed costs lower, making these clean, renewable alternatives more competitive with coal using conventional cost and return on investment measures and methods, even given their increasingly glaring inadequacies.

Billionaire Buffett Bets on Solar Energy

The “Oracle of Omaha,” who made his fortune by betting on technologies that appear underpriced, is now putting his money into solar.

The solar industry got a turbo-boost of both name recognition and mainstream credibility on Wednesday as a subsidiary of billionaire Warren Buffett’s investment company MidAmerican Energy Holdings announced plans to purchase the Topaz Solar power development from thin-film PV module maker First Solar. Terms of the deal were not disclosed.
