The heat that reaches the Earth from space has long been used to generate electricity, but can the concept work in reverse? Read on

Beaming solar power from space to Earth has long been talked about in theory, but now the first steps are being taken towards making it a reality. Read on

Installing solar panels tends to be a big commitment, often requiring what amounts to a small-scale home makeover. But now a startup has developed a new system for renters and homeowners who want both green power and convenience. Read on

Industries requiring high temperatures usually turn to fossil fuels for power. A Californian start-up backed by Bill Gates looks to change that. Read on

A US startup has developed a portable solar system for remote, offgrid areas. Transportable and packed into a freight container, it can also offer power quickly and easily to disaster-hit regions where infrastructure is scarce. Read on

A Portuguese startup has created a plug and play photovoltaic system that makes it easier than ever for people to become solar energy producers. Read on

How do you power a tropical island with little land, but over 300 days of sun a year? The solution: putting photovoltaic systems out to sea. Read on

Solar power trade-offs are a classic problem for clean energy solutions — the cheapest solar panels are usually the least efficient, because they don’t use complicated manufacturing processes. Read on

The USA currently ranks fourth in the world for solar power generation. But just how many solar panels is that? And who is using them? Read on
