Energy

The great green building makeover

Getting our homes and workplaces to be energy efficient has major benefits — but not when it is done one window at a time. Here’s why deep retrofits and biomaterials are key to more sustainable living.

The greening of planes, trains and automobiles

We need new fuels to transport people and goods around the globe as society moves away from coal, natural gas and oil. Here’s how things are shaping up.

Geothermal power heats up

Long confined to regions with volcanic activity, geothermal promises to become a much more versatile energy source thanks to new technologies

Nuclear’s role in a net-zero world

Is nuclear power a necessary part of the energy transition away from fossil fuels? As the debate rages on, new technologies and smaller reactors may be shifting the balance.

A big boost to Europe’s climate change goals

The bloc aims to become the first carbon-neutral continent. A new policy called CBAM will assist its ambitions — and may persuade other countries to follow in its footsteps.

Green shipping picks up speed

An international treaty aims to bring the shipping industry to net-zero emissions by around 2050. Can novel fuels, wind power and coordination on a global scale get it there?

How wind turbines could coexist peacefully with bats and birds

As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.

Pursuing fusion power

Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up.

The challenges and promises of climate lawsuits

Lawsuits against emissions-spewing governments and fossil fuel companies have established themselves as a key tool in the battle against climate change, but they aren’t always successful

The rise of green hydrogen in Latin America

In anticipation of future demand, several projects are underway in the region to produce this clean energy source
