Biofuels are combustible fuels created from biomass.
“Firewood is the oldest bio-fuel mankind has used, now we have biogas, gasohol and many more. Carbon dioxide is produced when these burn, but as long as the trees and plants are allowed to re-grow, burning them simply helps carbon on its way round its natural cycle.
What is biogas? If we collect the faeces from humans and farm animals and place them in a ‘digester’ we can mimic what happens in a cow’s intestine, and we get biogas. There are many such digesters in use all round the world, where the gas is used for cooking and lighting and the remains are a rich fertiliser.

Every year on April 22, over a billion people in 190 countries take action for Earth Day. From San Francisco to San Juan, Beijing to Brussels, Moscow to Marrakesh, people plant trees, clean up their communities, contact their elected officials, and more—all on behalf of the environment.
Earth Day focuses on the unique environmental challenges of our time. As the world’s population migrates to cities, and as the bleak reality of climate change becomes increasingly clear, the need to create sustainable communities is more important than ever. With smart investments in sustainable technology, forward-thinking public policy, and an educated and active public, we can transform our cities and forge a sustainable future. Nothing is more powerful than the collective action of a billion people.
As the global organizer behind Earth Day, Earth Day Network creates tools and resources for you to get involved with Earth Day in your community. Get involved!
