  • Refurbished Wind Turbines to Power the Developing World at a Profit

    The commercially-based Wind for Prosperity initiative may have devised a solution to meet growing demands for electricity in developing economies, where fossil fuels are expensive, difficult to access, and take a toll on environmental and human health. The venture works to refurbish wind turbines from Europe and re-deploy them in the developing world, providing clean and affordable power where it’s needed most.

  • Geothermal Energy in Developing Countries and the MDGs

    As the world continues to grapple with the challenges of balancing rapid development and energy needs against sustainability initiatives and conscientious practices, renewables continue to provide a growing, constructive alternative to fossil fuels. Geothermal energy in particular is a resource with vast potential, as unlike wind and solar it is constant (does not have low times for which energy must be stored) and it is accessible in dozens of countries. But it will require global cooperation to fully tap the potential and define a sustainable future in energy.

  • Green Roofs in Big Cities Bring Relief From Above

    New York City black tar roofs cause a number of environmental problems, including air pollution, heat absorption that raises energy consumption, and storm water runoff in the sewer system. Efforts to turn these old roofs into green spaces cool the buildings, enable the containment of more rainfall, reduce sewer discharge, generate energy, and absorb carbon emissions. New York City has a pilot program offering financial help for green roofs.
