energyRenewable energy will be equal or cheaper than fossil fuels in 2020

The International Renewable Energy Agency (IRENA) believes wind and solar will be equal or cheaper than fossil fuels by 2020. Prices could be as low as three cents per kilowatt-hour for onshore wind and solar photovoltaic projects over the next …

coolingRenewable power of 2050 will be powering air conditioners

The world has about 3.5 billion cooling appliances (fridges and air conditioners). That number is projected to grow to about 9.5 billion cooling appliances by 2050. If we actually want to deliver cooling for all, with no one left behind, …

economic impactWind Power costs at 2 cents per kilowatt hour

Technology advancements and cost reductions have driven wind power down to 2 cents per kwh. This is from the annual report released by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab). Key findings from …

californiaGermany and California could made a faster move to 100% clean power by adding instead of removing nuclear power

California and Germany could have mostly or completely decarbonized their electricity if they have invested in nuclear power instead of solar and wind renewables. If Germany did not begin a nuclear power phase-out in 2011, then they would still have …

energyUsing 82 Terawatts of solar and wind to Green the Sahara as a side effect would cost at least $82 trillion

Researchers simulated the effects of around 79 terawatts of solar panels and 3 terawatts of wind turbines. Computer modeling looked at the effect of covering 20 percent of the largest desert on the planet in solar panels and installing three …

desertCanada sized Solar and wind farms could make the Sahara Desert green again with double the rain

A team of scientists has concluded that deploying solar and wind farms across the region that the Sahara encompasses will produce significantly more rain, and therefore, natural vegetation, in the areas that they would exist. In what the study refers …
