Civic technology helps communities put power into their own hands - quite literally. New open source technologies can provide powerful tools to those looking to set up local renewable energy grids.

Many rural off-grid communities would benefit hugely from being hooked up to a solar power system. But which areas are most suitable for solar power installation? And which are most in need? A new earth observation software is using artificial intelligence and satellite imagery to bring power to people more accurately, efficiently and faster than before.

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

Cheaper and thinner solar power cells could lead to more affordable and more accessible renewable energy - for more people. But does it also bring new challenges?

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.

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.

Solar panel pollution is not something you often hear about, but one team is working to make clean power even cleaner.

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.

Chinese engineers hope to beam solar power all the way from space back to Earth - but is the plan feasible?
