How do we solve climate change? Do we eat less meat? Turn off the lights? Fly less? ‘No!’, I hear you say, ‘we need systemic action!’ To a large extent this is true, but as with all things related to climate change, it is not quite so simple. In this piece, I will be playing devil’s advocate and putting forward some of the arguments for why individual action is also important. Please do not take this to mean that I am a puppet of the corporations.
Some renewable technologies harness the vast mechanical power available from a planet that is in constant motion. Wave power generators (WPGs) are a possible energy source of the future, but how do they compare with their rivals?
Humans have been using biofuels for as long as we’ve been using wood to fuel our fires. In the last hundred or so years, however, we’ve begun to understand how plant matter can be converted into liquid fuels that could soon power a plane. In this piece, I’ll be looking at where biofuels are now and where they need to be if they are to significantly reduce CO2 emissions.
