We badly need new sources of clean energy to generate electricity, heat and power our industries, homes and workplaces. Up to now, we have relied on and used only fossil fuels to power our industrial and domestic activities. The byproducts of fossil fuels include: irreversible pollution and contamination of our Earth, climate change, global warming, and increase in pathogenic and medication-resistant diseases. Exhaustible fossil fuels are expensive to produce and distribute, and not everybody can afford them. Why not switch to natural, non-polluting, inexpensive, inexhaustible fuels such as solar, wind, water, etc., fuels? This is the timely message contained in TWENTY-FIRST CENTURY'S FUEL SUFFICIENCY ROADMAP. You can make this message realisable. Go on reading! Thanks.
