Adding more bioethanol to petrol is no way to go green
18 July 2019
Making “greener” fuels by adding bioethanol to petrol will wreck the environment, not save it. We need to focus on making electric cars work, says Michael Le Page
The race to green domestic heating and prevent climate catastrophe
14 November 2018
Household heating systems are huge sources of carbon emissions, but many countries are showing how existing technologies can fix the problem
Finally we can power the planet on renewables alone – here's how
6 June 2018
Ditching fossil fuels to go 100 per cent renewable is a dream within reach – thanks to new tech that keep things humming even when wind and sun aren’t there
We messed up our figures on how much carbon dioxide is too much
14 May 2018
Climatologists have tried to set a “carbon budget” that tells us how much greenhouse gas we can emit and stay below 2°C, but their efforts have only caused confusion
EU will limit the use of palm oil as car fuel but won’t stop it
14 June 2018
The European Union will make only minor tweaks to “renewable” energy policies that are actually increasing greenhouse gas emissions and driving deforestation
Graphene with ripples could help make better hydrogen fuel cells
28 March 2023
The one-atom-thick layer of carbon known as graphene can split hydrogen 100 times more efficiently than an equivalent mass of the best catalysts because of its strange nanoripples
Two-sided solar panels that track the sun produce a third more energy
3 June 2020
Double-sided solar panels that track the sun as it moves in the sky would produce 35 per cent more energy and reduce the average cost of electricity by 16 per cent
Changing how we make solar panels could reduce their carbon emissions
31 July 2020
Although solar panels are a source of renewable energy, making them has an environmental impact. A new type of panel has a lower carbon footprint than traditional silicon ones
Metallic hydrogen would be the ultimate fuel - if we can make it
1 January 2020
The universe’s most common element could also be its most wondrous. Two different groups of researchers say they've made it - but can either claim withstand scrutiny?
