Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides and geothermal heat—which are renewable (naturally replenished). Today, about 20% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning.
Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18 percent of the country’s automotive fuel. Ethanol fuel is also widely available in the USA.
We concentrate on pure plant oil (biomass) energy applications: pure plant oil – rapeseed oil – as diesel engine fuel.
