The Latin American country of Costa Rica has achieved an impressive milestone in green energy production by generating 100 per cent of its energy from renewable resources, with a combination of hydropower and geothermal for 75 days in a row.
Thanks to the favorable rainy conditions in the first months of the year, four of Costa Rica’s hydropower plants — Arenal, Cachí, La Angostura and Pirrís — are generating nearly enough electricity to power the entire country. Using a mix of geothermal, solar, and wind energy sources, the nation of 5 million inhabitants hasn’t needed an ounce of coal or petroleum to keep the lights on since December of 2014.
What an extraordinary effort by a small nation! Way to go!
While access to clean drinking water remains an issue in many parts of the world, there’s no shortage of water on the planet: 97%
of Earth’s water can be found in our oceans.
Turning the ocean’s
saltwater into freshwater is generally an elaborate process that
requires a lot of energy, but a team of scientists at Rice University’s
Center for Nanotechnology Enabled Water Treatment (NEWT) have created a
new method using nothing but sunlight.
thanks to researchers at Rice University, an off-grid desalination
technology is available requiring only solar energy.
At a reverse auction in Rajasthan on Tuesday, power companies Phelan Energyand Avaada Power each offered to charge 2.62 rupees per kilowatt-hour (kWh) of electricity generated from solar panels they hope to build at an energy park in the desert state. Last year’s previous record lowest bid was 4.34 rupees per kWh .
Analysts called the 40% price drop “world historic” and said it was driven by cheaper finance and growing investor confidence in India’s pledge to dramatically increase its renewable energy capacity.
