  • 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 ...

  • Siemens Takes A Good Step Towards Energy Efficiency

    The contemporary world today is facing a lot of economic and environmental challenges. It is important to find a quick and sustainable solution. Siemens, the market leader in power technology, concentrates on renewable energy, solar energy and wind power especially.

  • EU to reallocate €115m for energy efficiency projects

    The EU has approved reforms that will free up €115m stimulus cash to be reallocated for energy efficiency projects with an impact on economic recovery. The Industry, Research and Energy Committee of the European Parliament approved reforms yesterday to EU rules on financial assistance that will free up about €115m (£95.6m) in otherwise unspent funds. The EU funds could be used to ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The natural gas revolution: Good or bad for energy efficiency?

    If there were an equivalent in the energy industry to Time Magazine’s Person of the Year, natural gas would be this year’s winner. The dramatic rise in natural gas supply, and fall in price, has reconfigured the energy scene in the United States, suddenly creating a bounty of domestic energy, driving down wholesale power prices and speeding retirement of polluting coal-fired plants. ...

  • Energy efficient ferrero group invests in GEM

    Thermal Energy International Inc is pleased to announce that Energhe S.p.A. has made Thermal Energy International’s GEM venturi orifice steam traps its steam trap of choice following rigorous testing at Ferrero Group’s headquarters in Alba, Italy.   Founded in 2007 by parent company, Ferrero Group, Energhe S.p.A. develops energy efficient projects and financial savings for ...

  • Efficiency is cheap, but will it sell?

    Expect to see this number a lot in energy discussions over the next few years: 2.5 cents/kWh. It is the average cost of energy efficiency, a figure pegged this week in a new report by the American Council for an Energy Efficient Economy. This number is big news because it is so small. As a resource, energy efficiency beats out all conventional power sources on price. Moreover, it’s a price that ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Wind power growth in the US

    Last year was a banner year for renewable energy in the United States, especially for the wind industry. As the recent REN21 Renewables 2007 Global Status Report highlights, the industry broke all past global records, installing 5,244 megawatts (MW) of new wind energy capacity in 2007, or 30 percent of all new U.S. capacity added. This brings the cumulative national total close to 17,000 ...

  • The Future Cost of Wind Power

    Chapter 1 The economics of wind power Wind power is capital intensive with most of the investment required upfront. The largest capital cost component is the turbine itself which can account for between 40% and 80% of the total capital cost of an onshore wind installation. Costs offshore are higher because of the more expensive operating environment and the greater difficulty establishing ...


  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Create new jobs & cut emissions by investing in renewable energy efficiency

    At a time when major US companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both ...

  • Renewable, clean energy: the petroleum footprint - wind farms under analysis

    This paper presents a methodology to assess projects for the generation of clean, renewable energy. Such methodology is applied here to estimate the consumption of fossil fuels (referred to as 'oil'), required for the construction, operation and maintenance of a wind farm consisting of 97 turbines of 3 MW each. Results show that such consumption represents a conservative 8–9% of the total energy ...

  • Efficiency stimulus will lower energy bills, says federal report

    Depending on your position, the federal stimulus money is either a jobs builder or a national budget buster. The Energy Information Administration offers another take. In a recent analysis, the EIA finds that stimulus money should reduce what consumers and businesses pay to heat, cool and light buildings. The federal agency this month updated its annual energy outlook to compare how energy ...
