energyGlobal Solar and Wind has to increase by about five times to provide all of annual increase in electricity

Global solar power is projected to go from 500 TWh in 2018 to about 900 TWh in 2022. Global wind power is projected to go from 1200 TWh in 2018 to about 1600 TWh in 2022. This will cost over …

chinaGlobal Renewable power spending has been virtually flat for seven years and most countries will need expensive grid upgrades to handle more solar and wind

Global investment in renewable energy (Solar, Wind, Hydro and biofuel) edged up 2% in 2017 to $279.8 billion, taking cumulative investment since 2010 to $2.2 trillion. The level of global renewable power spending has been virtually flat for seven years. …

airplanesAirbus has solar powered stratosphere drone that has flown for nearly 26 days

An unmanned Airbus drone aircraft, a 75 kilogram Zephyr, flew for almost 26 days. It will offer local satellite-like services and runs on solar power. It flies in the stratosphere at an average altitude of 70,000 feet and has a …

energyOrganic Solar Cells reach higher efficiency and semi-transparent versions will add power generation to windows

A new study pushes organic solar cell efficiency beyond 17% with the authors saying that up to 25% is possible. This is important because according to estimates, with a 15% efficiency and a 20 year lifetime, organic solar cells could …

elon muskElon Musk going from two public companies in 2016 to none

Elon Musk Tesla and Solarcity were both publicly trading from 2012 to 2016. Tesla went public June 29, 2010. Solarcity went public Dec 12, 2012. Solarcity was bought by Tesla in a $2.6 billion all-stock transaction Nov 21, 2016. Elon …

batteriesIn California, 100% Solar and Wind in 2045 will need $350 billion in energy storage

In California, both wind and solar generation are about ten times less in the lowest months versus the top three months. If California reaches the 80% mark for renewables there will be massive amounts of surplus generation during the summer …

energyBreakthrough could triple the energy collected by solar to 60% efficiency

Current solar cells are able to convert into electricity around 20% of the energy received from the Sun, but a new technique has the potential to convert around 60% of it by funneling the energy more efficiently. UK researchers can …

energySpace Based solar to replace oil using the Nuclear Turbo rocket

Keith Henson has some concerns that high volume flight rates for the SpaceX BFR could be a problem for the atmosphere if it was used for many thousands of flights to place massive amounts of space-based solar power to replace …

energyWorld record for direct solar water-splitting efficiency

Researchers have increased the efficiency of producing hydrogen from direct solar water-splitting to a record 19 percent. They combined a tandem solar cell of III-V semiconductors with a catalyst of rhodium nanoparticles and a crystalline titanium dioxide coating. Teams from …

energyA voltage breakthrough with perovskite solar cells to edge closer to commercialization

A new technique has produced the highest performing inverted perovskite solar cell ever recorded. A team of researchers from Peking University and the Universities of Surrey, Oxford and Cambridge detail a new way to reduce an unwanted process called non-radiative …
