Floating solar farms have several advantages, not the least of which is they don’t use up valuable land in densely populated areas. China has over 100 cities with populations of more than 1 million. The US, by comparison, has 10.
Floating solar power plantThe panels help to conserve precious freshwater supplies by lowering the amount of evaporation into the surrounding atmosphere. In return, the water keeps ambient temperatures around the solar panels lower, which helps boost their efficiency and limit long-term heat-induced degradation.
The most interesting thing about the floating solar power plant in Huainan, however, is that the lake supporting it was created by rain after the surrounding land collapsed in a process known as subsidence following intensive coal mining operations over a period of years. Anhui province is rich in coal reserves and has been the source of much of the coal used to power the Chinese economy.
The point is not that solar should not be considered, but that it should be considered, warts and all, alongside coal, nuclear and hydro with all their drawbacks. Too often, renewables' drawbacks and deficiencies are glossed over, not the least of these being that are unlikely ever to meet global energy needs

Fights over rooftop solar generally focus on "net metering," but the challenge to utilities is far greater than that, and if they hope to survive, their response must be more ambitious.
Self-cooling, longer lasting and more efficient solar cells are within reach simply by adding a thin layer of glass. A paper
As utilities see how distributed solar, aided by new storage tech, can chip away at their monopolies (and profits), they're fighting back.

Remember Solar Roadways, the start-up that received a $100,000 contract from the Department of Transportation to develop road systems with embedded digital signage and dividing lines, all powered by the sun? As it turns out, the company's prototype performed well -- so well that Solar Roadways is now looking to go big-time, and it's asking for your help to...
