solar powerAlmost 90% of the World’s photovoltaics today are based on some variation of silicon. Solar energy is an essential part of the global move toward clean, renewable energy, and it is critical that the growing solar photovoltaic industry is itself truly safe and sustainable.

Clean energy vs. oil

ALTERNATIVE ENERGY

 When oil prices fall, low-carbon sources of energy such as wind and solar power may seem less attractive to investors, creating doubts about the pace of the world’s transition to clean energy.

Some renewable energy projects which aren’t completely bedded down are certainly … delayed but at the same time, (the low oil price takes) off the market very expensive oil projects. Tar sands and exploration in the Arctic have become less attractive due to the oil price crash. [1] Continue reading
