  • The Inevitability of Change and Resistance to Energy Efficient Lighting

    Change is inevitable. It is one of the only constants in life, and as the saying goes, nothing ever stays the same. Despite the truth behind this, most societies and cultures have historically demonstrated a resistance to change. Perhaps nowhere is this currently more evident than in global efforts to promote a change to energy efficiency awareness and the new technologies intended to speed the ...

  • Costs and Benefits of Energy Efficient Lighting and Technology

    In developed nations, lighting accounts for a large portion of the entire amount of electrical power consumed. In the United States, lighting is responsible for approximately 20% of total electricity consumption. In Canada, up to 50% of the electricity used in residential areas is consumed by lighting. In the US and Canada, lighting accounts for about 35% of the electricity used in commercial ...

  • Much light, little heat efficiency

    Energy efficiency in the US is much light and little heat – literally.  Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste.  “Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are off the radar,” said Rob Thornton, president of the ...

  • A new light on saving energy

    Some 80,000 dynamic street lights have been installed in Europe over the past few years. Quite a modest number if you consider that there are some 91 million light points in Europe. The city of Oslo alone has 54,000 street lights. A dynamic street light is a system that tells you exactly how much energy each single luminary is using and when its lamp needs to be replaced. It adapts the light ...

  • Improved Lighting Efficiency: German Wrecking Company

     Background German Wrecking Company (GWC) is a small business that specialises in the wrecking and storage of Mercedes Benz and BMW automotive parts and panels. It differs from many auto dismantlers as it is totally roofed to avoid contaminated rainwater from car bodies entering the stormwater system. This puts German Wrecking in line with 'best practice' in this industry, but also ...


  • Obama, energy efficiency & accountability

    Not once, but twice President Obama mentioned the importance of energy efficiency in his state of the union address January 27. His support for the resource is no surprise; his administration has channeled $20 billion toward energy savings programs. Obama made clear that going into his second year his support will not waver.“I know that there are those who disagree with the overwhelming ...

  • Hot sectors for energy efficiency

    It’s clear that the energy efficiency industry is undergoing an unprecedented boom, spurred by state and federal support and movement toward a smarter grid. But for those in the industry, where exactly can the new business – and the jobs – be found?Two new reports by Colorado-based Pike Research shed some light.After years of focusing on bringing efficiency to manufacturing, policymakers are ...

  • Energy efficiency and Weight Watchers

    By Elisa Wood April 27, 2011 We’ve been hearing for years that the energy efficiency industry needs to find its equivalent to the cell phone. These days industry folks refer to it as the ‘killer app,” the revolutionary ...

  • Obama and the reinvention of energy efficiency

    The energy efficiency industry received a nice boost this week during President Barack Obama’s State of the Union address. Obama called for cutting energy use by half over the next 20 years. Such attention comes at a significant point in the history of the energy efficiency movement, one when it appears to be re-inventing itself again, and in a way that ...

  • Energy efficiency without trying (and with)

    John Lennon wrote that life is what happens to you while you’re busy making other plans.  Apparently, the same is true of energy efficiency. Energy savings happen when we’re busy doing other things – Internet-based things specifically. We use email, bank online and download music not to save energy, but to make life easier and more interesting.  Energy efficiency is a ...

  • A no-granola case for energy efficiency

    I attended a green energy conference nearly a decade ago in Washington, D.C., where several speakers expressed astonishment at the audience’s clothes. People were dressed in business attire. Where were the ponytails? The Birkenstocks? The event marked a new age for green energy, the beginning of its migration from counter-culture to corporation. Today green energy is, well, more like ...

  • A Better Mousetrap: High-Efficiency Halogen Lamps Are a Superior Energy-Efficient Lighting Solution for Existing Recessed Downlights

    For many homeowners, especially those with children, the kitchen is the most lived-in room in the house. It's a gathering place, a workspace, a study area, an entertainment venue and of course, a room in which to enjoy meals together. Thus, it's not uncommon for kitchen lights to be switched on for four or more hours per day. This presents a legitimate opportunity to save money and reduce air ...

  • Lethal light

    From radio signals to gamma waves, the electromagnetic spectrum offers considerable potential to prepare and preserve food products. Knowing precisely which wavelength in the spectrum to apply to a particular need is only the first step, however: scientists and engineers also need to fabricate systems that can withstand the rigors of an industrial environment. The application of UVC, short-wave ...


  • What energy efficiency type are you?

    By Elisa Wood July 29, 2010  Not so long ago, consumers seemed to like energy efficiency just a little bit more than going to the dentist. Clearly that has changed, as evidenced by the recent run on appliance and home retrofit subsidies in several states. Greens are no longer alone in swooning over front loader washing machines and geothermal heat pumps. But who exactly are these new ...

  • How risky are energy efficiency investments?

    Last week’s announcement of $8.3 billion – and possibly as much as $54.5 billion – in US federal loan guarantees for nuclear power plants sparked debate about risk of default on loans. What are the chances the plants will be built? Critics unearthed a Congressional Budget Office report citing a 50% risk the projects will fail. The Department of Energy countered that the report is seven years old ...

  • The 14 best states for energy efficiency

    Once a “token gesture,” energy efficiency is now increasingly becoming a “first fuel” — the resource utilities seek before any other, even before renewable energy or other in-favor generation sources. So says the report, “Meeting Aggressive New State Goals for Utility-Sector Energy Efficiency: Examining Key Factors Associated with High Savings,” issued today by the American Council for an ...

  • Energy Efficiency prospects: What to watch

    Events unfolding in two US Northeast states – New York and Massachusetts – signal increased business opportunity for energy efficiency companies, green architects, lighting contractors, smart grid innovators and others in the business of saving energy. First, the energy efficiency world should keep an eye on debate over the possible shutdown of the Indian Point nuclear power plant in ...

  • Utilities: friend or foe of energy efficiency?

    With oil prices so high, talk again has turned to making the U.S. more energy efficient. In the power industry, utilities have been typically charged with this mission. Or to more aptly describe it, they have gotten dragged, kicking and screaming, into helping their customers use less electricity. You can’t blame them for resisting. An electric utility is a business that makes its money ...

  • Building Experience: Energy Efficient Buildings

    Issue: The development of large commercial, governmental and even residential buildings which take advantage of energy efficient design and incorporate on-site renewable energy sources could have a major impact on achieving and maintaining Kyoto targets on reducing carbon dioxide (CO2) emissions in the future. Although demonstration sites across Europe have been built, the lessons learnt in their ...
