Biofuels Are Not a Green Alternative to Fossil Fuels

6 months ago
Powering cars with corn and burning wood to make electricity might seem like a way to lessen dependence on fossil fuels and help solve the climate crisis. But although some forms of bioenergy can play a helpful role, dedicating land specifically for generating bioenergy is unwise.

With a temperature of nearly 11,000°F, the Earth's core is hotter than the surface of the sun and humans have found a way to safely harness a small portion of that heat energy to generate power. It's called geothermal energy.

Should the UK end tax breaks on burning wood for power?

A new report from climate change think tank Ember reveals the cost of burning wood for power, with energy billpayers committed to subsidies of more than £13 billion, including £10bn at Drax power station alone. In addition to the direct subsidy, they estimate biomass generators are receiving carbon tax breaks of £333 million a year.
