The world can run on 100 percent renewable energy, sooner and cheaper than most think

100 Percent Renewable Energy is Within Reach

There are no technological or economic reasons why we cannot completely replace fossil fuels with renewable sources of energy. In addition to curbing climate change causing greenhouse gas emissions, renewable energy also improves human health. Minimizing climate impacts and reducing health costs would generate trillions of dollars of cumulative savings. The idea that the world can be powered entirely by…

Considering the global potential for solar energy

Infographic: Could the World Be 100 Percent Solar?

What is the global potential of solar energy? – Perhaps the only thing more unrealistic than the idea of a modern world powered 100 percent on solar energy is the idea that extracting every last bit of fossil energy is sustainable, good for the long-term economy or a habitable planet. Building a new energy economy is fraught with many challenges….

graphene may bring huge breakthroughs in many areas of human society

Graphene May Herald Green Miracles

Graphene may provide technological solutions to a host of issues including the climate crisis. It is as hard as diamond, in fact, it is two hundred times stronger than steel, yet lighter than a feather, making it both ultra-light and durable. This, inexpensive tough new material is also as flexible as rubber and it can heal itself when it is…
