We have all the technologies needed to make the electric grid run on renewables and lower pollution. What are they and what are the barriers to adopting them widely?
Japan’s global influence has waned in recent years. Showing that renewables can decouple emissions from economic success could help the country find its niche and spark a race to power the Earth.
Twelve power projects are in the running for federal government dollars: six pumped hydro, five gas and one coal. It’s clear which one shouldn’t be on the list, for economic and environmental reasons.
There are some good explanations for the mismatch between regional support for climate action and the areas where renewable energy is making the biggest inroads.
Solar roadways have been promoted as a way to fight climate change, put people to work and make driving safer. But on closer inspection the reality is less than impressive.
The first commercial-scale installation of rooftop solar cells, printed with specialised inks, is a step towards an energy future in which solar power can be stuck to any roof or structure.
The Trump administration’s Affordable Clean Energy Plan would help the declining coal industry, but a study shows many coal workers could transition to a new industry – solar – and earn more money.
Two business professors spent five years studying Walmart’s ambition project to bring sustainability to its millions of budget-conscious customers – a plan that began with the birth of a granddaughter.
Silicon is cheap and a good semiconductor, but it’s bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.
