  • Time to export energy efficiency?

    We keep hearing that China is going to become a really big deal in world energy markets. But it wasn’t until I read this statement by Jane Henley, CEO of the World Green Building Council, that I grasped the scope of its coming influence: "China is projected to build the equivalent of 10 New York Cities over the next decade.” For some, such rapid economic expansion by China is cause ...

  • Energy efficiency, the Nerd

    The renewable energy business has done a remarkable job at positioning itself in the public psyche as the ‘it girl’ of our era.  Just about everyone – politicians, celebrities, major industries – likes to be seen as pro-renewable. But if renewable energy is the girl that everyone wants to be ...

  • How to make energy efficiency affordable

    Energy efficiency is a tortoise in the green energy race. Not glamorous like solar, wind or smart grid, it tends to plod along in the back of the pack, attracting little media attention. But being last can be a good thing; you learn from the frontrunners. Such is the case when it comes to financing. EE is beginning to borrow from strategies that have spurred tremendous growth for solar and other ...

  • Energy Efficiency and the annoying guy next door

    Who would have thought backyards would cause so much trouble for the North American energy industry? First came the NIMBYs, the not-in-my-backyard protesters who block power projects from being built near them. And now we have the GIMBBYs – the give-me-a-bigger-backyard homeowners who are unwittingly getting in the way of energy efficiency. GIMBBYs aren’t worried about seeing wind ...

  • Ireland`s growing potential in Wind Energy

    For a nation battling double digit unemployment and near total dependency on imported fossil fuels to meet its energy needs, the growing job creation potential of renewable energy in Ireland is like a breath of fresh air. The Irish government has been battling growing unemployment for the last five years - currently at 14.8 percent - while at the same time seeking ways to lower the country's ...

  • Wind Energy Technologies: Technology, Market and Costs

    Technology Overview   These large wind turbines turn Midwestern wind into utility electricity. Wind turbines convert the power in the wind into electricity. By extracting the kinetic energy in the wind, wind turbines generate mechanical power. In the past, mechanical wind machines were widely used for specific tasks, such as pumping water or grinding grain. Today, wind ...

  • Energy and exergy assessments for potential wind power in Turkey

    The main objective of the study is to estimate wind power potential of Turkey and provide suitable data for evaluating potential wind power by using the wind data collected at 23 different wind-monitoring stations. In this study, energy and exergy analyses of wind power are used to estimate wind power potential in these areas. Exergy analysis of wind power is investigated according to air ...
