Concentrated Solar Power, or CSP, is another possible technology to generate electricity from the sun. While it can store energy and thus provide electricity after the sun went down, the global current capacity is still around 5,000 MW, compared to solar PV’s being above 220,000 MW.
Al Gore did it again in another TED Talk in the end of last month. In 20 minutes he managed to show how critical our climate situation is but also brought a lot of optimism as solar and wind are beating all past predictions on how fast and big they are growing.
After reducing our trash at the source and composting and recycling what can be, waste to energy is a good way to avoid landfilling while producing both heat and electricity. China is thus turning to this solution to answer its most pressing challenges.
Here is some research we might see one day off the coasts around the world : giant 50 MW offshore wind turbines, with blades as long as 200 meters (650 feet). That’s two and a half times longer than any existing wind turbine blade.
With renewable energy sources ramping fast, it is no surprise that even the generally conservative International Energy Agency believes that solar, wind and the likes will the primary electricity source globally by 2030.
Smart infrastructure choices from cities worldwide would save them $17 trillion (15.2 billion euros) by 2050. The solutions – renewable energy, public transportation, energy efficiency – are not new but the lens of this new study is interesting.
