Supervolcanoes could be the key to our battery-powered future

In order to rely on renewable energy sources like wind and solar power, the world is going to have to find efficient ways to store electricity, saving it up for times when the wind is not blowing and the sun is not shining.

One of the leading contenders for large-scale storage at the moment is the lithium ion battery. Elon Musk has promised to build a 100MW batteryin Australia, and energy company AES is constructing a facility of the same size in LA.

Currently, most of the lithium used in these batteries comes from Australia and Chile. But the lithium supply needed to provide large-scale battery storage could come from an unexpected place, according to a new study. Supervolcanoes

Solar power explained: How do solar panels work?

Life on Earth could not survive without the sun. It provides light and heat, the seasons and the day and night cycle necessary for life to have evolved. Today, we’re exploiting the energy from the sun to power our lives and experts say one day, this source of energy may be all we need. But, behind the headlines what exactly is solar power and how do we harness it?

What is solar power?

There are two main types of solar energy: photovoltaics and concentrated solar power (CSP), also known as concentrated solar thermal.

Bottling Britain’s wind energy

To go green, the UK will need to make the most of wind power. Teams of engineers are racing to do just that

WE’VE got six years. By 2020, 20 per cent of the UK’s energy should come from renewable sources, to meet the terms of a European Union agreement. It is likely that most of that energy will come from wind, which the UK gets plenty of. The challenge is working out how best to store the power.
