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.

Nuclear energy has some distinct advantages in strengthening the external dimension of energy supply security. These include:
• Nuclear power plants produce electricity domestically. Their capital and labor inputs are also provided domestically. With more than 90% of its inputs in terms of value sourced domestically, it can be considered a largely domestic source of energy and electricity.
• Of course, a majority of OECD countries import part or all of their requirements of uranium plutonium. (more…)
In today’s tough economic times and with the increasing prices of gas and oil, finding alternative sources of energy should be our top priority. These alternative energy solutions are not only cheaper to install and maintain but also can help save our dying environment.
There are numerous sources of affordable and environmentally-friendly fuels available. You can opt for biofuels, hydroelectric power system, wind energy, or solar power system installed right at your very own home. Among these sources of energy, building solar power system is easier and the most viable one to achieve. (more…)
Energy scarcity is making people adopt the concept of solar power homes all over the globe. When the oil prices skyrocketed during 2008, it reminded people that dependency on fossil fuels is not a wise strategy. Since then many initiatives have been launched all over the world to find out alternate energy resources. Large companies are spending huge amount of money on research for development of alternate fuels like bio diesel, ethanol blended fuels etc. (more…)
