ISIS Press Release 30/07/08
Life cycle assessments are revealing just how much we can reduce greenhouse gas emissions and save on energy use with different renewable options - Dr. Mae-Wan Ho
Electricity generation a major polluter
The electricity industry currently contributes about 37 percent of the world's carbon emissions, predominantly from burning fossil fuels while electricity is generated . The best option for reducing carbon emissions is to substitute renewable energy resources for fossil fuels. Our recent report  Food Futures Now (ISIS publication) shows how a radical change in the way we produce and distribute food as well as energy can indeed free us from fossil fuels altogether.
Renewable energies such as solar and wind do not emit carbon dioxide while generating electricity, and have the further advantage that it can improve the efficiency of energy use considerably. Big power plants are located far away from most users, so the electricity generated has to be transported long distances over power lines where more than 7 percent may be lost before it is used. In addition, some
60-70 percent of the energy is lost as 'waste' heat while generating electricity. In contrast, solar panels and wind turbines are readily installed on or near homes and farms and the electricity generated as well as the heat can be consumed directly without much loss.
