Hybrid Electric Vehicles - Better Than Ethanol
Mario Osava
RIO DE JANEIRO, Apr 17 (IPS) - Hybrid electric vehicles (HEVs) are the best way to achieve a drastic reduction in greenhouse gases produced by vehicle exhaust fumes, until hydrogen-powered models become viable. They are even more environmentally-friendly than the use of biofuels.
Powered by an internal combustion engine and an electric motor, HEVs are becoming an attractive alternative in the light of the most recent reports by the United Nations Intergovernmental Panel on Climate Change (IPCC), which recommend urgent measures to curb global warming, say Brazilian experts.
Automotive engineering professor Marcelo Massarani at the Polytechnic School of Sao Paulo University told IPS that HEVs can cut pollution caused by vehicles powered by fossil fuels by 80 percent, "and sometimes by up to 90 percent."
An HEV is still 10 to 20 percent more expensive to buy than a conventional car, but in Sao Paulo there would be an average net saving of 18,000 reals (8,800 dollars) over the life of the vehicle, Juliana de Queiroz concluded in her master's thesis, which was supervised by Massarani.
