Solar PV efficiency new record hit : 44%

To Treehugger : “ The National Renewable Energy Laboratory (NREL), and their industry partner Solar Junction, have just set the bar even higher in the race for ultra-high-effiency PV cells by achieving another world record of 44% efficiency. “ But wait, there is more as to another article solar PV panels could soon be 50 … Read more

Soon in our houses, see-through solar ?

To Renewable Energy World : “ Last week, researchers announced they had produced the largest see-through organic solar module to date — a 170 square centimeter functioning module that is 14 times larger than the last iteration.”

” The technology was produced through a collaboration with researchers at the National Renewable Energy Laboratory (NREL) and the organic solar company New Energy Technologies.”

This is exciting, but we shouldn’t get our hopes to high as for the moment, these solar panels have a low efficiency of only four to five percent.

Prepare for a wind energy century

Last week the US National Renewable Energy Laboratory (NREL) released a report stating the United States could get twenty percent of their electricity by offshore wind by 2030.

On the other side of the Pacific Ocean, China installed 13,8 GW of capacity in 2009 alone, to reach a capacity of 25,8 GW. A report notes that the wind capacity could reach 250 GW by 2020. These are staggering figures.

Meanwhile, the Global Wind Energy Council (GWEC) notes that this energy source could provide a fifth of global electricity by 2030. Let’s have a detailed look at each of these news.

90% more efficient air conditioning

As the world is heating up because of global warming we need more air conditioning systems. This is why the latest invention from the U.S. National Renewable Energy Laboratory may change the world.

Indeed, to the MIT Technology Review, the NREL have created ” a new air-conditioner design that (…) will dramatically increase efficiency and eliminate gases that contribute to global warming. “

Using indirect evaporative cooling, and desiccants this invention would use up to 90 percent less energy and wouldn’t need CFCs to operate.
