A Quote by Saul Griffith
Conventional turbines only work up to 200 feet, but capturing a small fraction of the global wind energy at higher altitudes could be sufficient to supply the current energy needs of the globe.

Windmills installed around the world converting their direct current into alternating current and feeding the electric energy into the world network can harvest the planet Earth's prime daily energy income source-the wind--and adequately supply all the world's energy needs
We need to bring sustainable energy to every corner of the globe with technologies like solar energy mini-grids, solar powered lights, and wind turbines.
But that's not enough: To maintain energy security, one needs a supply system that provides a buffer against shocks. It needs large, flexible markets. And it's important to acknowledge the fact that the entire energy supply chain needs to be protected.
Sunlight and wind are inherently unreliable and energy-dilute. As such, adding solar panels and wind turbines to the grid in large quantities increases the cost of generating electricity, locks in fossil fuels, and increases the environmental footprint of energy production.
I expect an energy bill to increase and diversify supply and stabilize energy prices - not drive up energy costs in one part of the country to subsidize energy in another region.
One of course is to insure greater supply of energy for California's needs now and in the future in the sense that we are in discussions with representatives of Oregon and Washington, where they do have a surplus supply of energy available, and at what we hope will be a very reasonable price.
Europe needs a clear and more collective and cohesive policy on security and energy supply. Today the issue of security of energy supply is only really considered at a national member-state level, but in reality we need a much greater European-wide approach on this issue.
A large-scale wind, water and solar energy system can reliably supply the world’s needs, significantly benefiting climate, air quality, water quality, ecology and energy security ... [T]he obstacles are primarily political, not technical.
I don't think America can just drill itself out of its current energy situation. We don't need to destroy the environment to meet our energy needs. We need smart, comprehensive, common-sense approaches that balance the need to increase domestic energy supplies with the need to maximize energy efficiency.
America is home to the best researchers, advanced manufacturers, and entrepreneurs in the world. There is no reason we cannot lead the planet in manufacturing solar panels and wind turbines, engineering the smart energy grid, and inspiring the next great companies that will be the titans of a new green energy economy.
By the year 2000, such renewable energy sources could provide 40 percent of the global energy budget; by 2025, humanity could obtain 75 percent of its energy from solar resources.
The sunlight ... that strikes Earth’s land surface in two hours is equivalent to total human energy use in a year. While much of that sunlight becomes heat, solar energy is also responsible for the energy embodied in wind, hydro, wave, and biomass, each with the potential to be harnessed for human use. Only a small portion of that enormous daily, renewable flux of energy will ever be needed by humanity.
Surveying the available alternative energy sources for criteria such as energy density, environmental impacts, reliance on depleting raw materials, intermittency versus constancy of supply, and the percentage of energy returned on the energy invested in energy production, none currently appears capable of perpetuating this kind of society.
Hopelessly uneconomic on any substantial scale, since it requires a conventional power back-up for when the wind stops blowing, forests of wind turbines are rightly regarded in most countries as an environmental monstrosity.
A joyous person abounds with energy and feels buoyant, because he or she is running a higher frequency current of energy through his or her system.
We want a plan for a clean energy future...an end to global warming...Moms know about sustainable energy. After all, mother love is an unending supply and it keeps kids healthy.
