The World Commission on Dams (WCD) was formed in 1998 by a joint initiative of the World Conservation Union (IUCN) and the World Bank (WB) after a historic meeting of leading dam proponents and opponents in Switzerland, with proceedings reported by Dorcey and others. The WCD was asked to discover the truth about the hydropower energy facts, hydropower energy pros and cons, cost, effect, and benefit of large dams and it functioned independently for 2 years at a cost of $10 million. The money was well spent, and at the end of that period the WCD produced a comprehensive report and numerous support documents, and then dissolved itself. The report and support documents remain on the Internet available to all, and they have changed forever the debate about dams. (more…)

Approximately 40% of Earth’s population is ‘‘off the grid,’’ mainly in developing countries. Wireless power transmission envisioned by Nikola Tesla a century ago is feasible today. Microwave beams can propagate power efficiently along lines-of-sight over long distances. Orbiting microwave reflectors could form the basis of a global electric grid.
An advanced technology path to electrification is the solar power satellite (SPS) proposed by Peter Glaser. Solar flux is about 10 times higher in space outside Earth’s shadow cone than the long- term average at the surface of spinning, cloudy Earth, and power from space can be beamed by microwave efficiently through cloudy skies to the surface where it is needed.

The broad range of home solar energy systems are mostly known as Photovoltaic Systems (PV) or Thin Film Solar Technology. The system applies solar panels to create electricity for use in individual homes and cross-feeding in a electric grids with electricity to give supply to other city or municipality. Several countries around the world have realized the enormous potential of solar energy supply and place the necessary systems are able to make this a very successful energy alternative. (more…)

Today, photovoltaic cells only contribute a small proportion (approximately 0.04 percent) of total electricity in the United States. At the same time the production of solar panels has growth rapidly per year by around 20% growth in the 1990s and photovoltaic panels prices decreases every year. Annual worldwide solar panel production (including solar panels with homemade solar power homes) is about 400 MW per year. Based on the total cumulative capacity figure, it is already reaching 2 GW.
