  • 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 ...

  • Hurricane HR Cyclones to capture fine fly ash particulate enabling the use of wood waste fired thermal oil heater for Sonae Indústria - Case Study

    The company was forced to use a natural gas fired hot gas generator for drying fibre despite having the necessary amount of thermal energy available in the exhaust stream of a wood waste fired thermal oil heater. The problem of using the biomass thermal oil heater laid on the emission of fine burnt and unburnt particulate which were carried over with the dried fibre and finally deposited on the ...

  • 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 ...

  • 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 ...

  • How to grow a solar energy garden

    Getting energy from the sun is a great idea. However, installing solar panels house-by-house is slow, costly and cumbersome, and downright inefficient if the goal is to bring solar to the masses. This problem troubled Paul Spencer after he built his own uber-efficient, custom solar home near Aspen, Colorado in 2004.  The engineer and serial entrepreneur wondered how he could replicate his ...

  • Changing the energy game with the ‘power of one’

    Who among us has not eagerly described the smart meter to a non-energy person only to be greeted by a blank stare, or worse the retort: “Why would I want to track my electricity costs all day?” You try to explain the profound applications: smart appliances that talk to the power grid, consumer clubs that sell energy savings, your car serving as a power plant. But the conversation then ...

  • Implications of renewable energy for women in Sudan: challenges and opportunities

    In Sudan, electricity reaches only about 30% of the population, mainly in urban areas. Hence, a major problem for rural people is the inadequate supply of power for lighting, heating, cooking, cooling, water pumping, radio or TV communications and security services. Petroleum product supplies, including diesel, kerosene and liquid petroleum gas are irregular and often subject to sudden price ...

  • Meeting the world’s growing energy needs - a strategic perspective

    Clarence P. Cazalot, Jr., President & CEO of Marathon Oil Corporation, participated in a CEO Dialogue on The Future of Energy at GLOBE 2010. The focus of that Dialogue was on Leadership in the energy sector, which is perhaps more vital than in any other industrial sector in the global transformation to a lower-carbon economy. This article is a concise overview of the points Mr. Cazalot made ...

  • What stops banks from lending to energy efficiency projects?

    Four years after the US credit market crashed, energy efficiency projects continue to struggle to secure financing. What’s the problem? A slow economy, of course. But when it comes to energy efficiency – and on-site renewable energy – the problem runs deeper. It’s not lack of interest in green energy. To the contrary, says Angela Ferrante, director of alternative energy ...

  • Is nuclear power our energy future — or a dinosaur in a death spiral?

    Identical data yield drastically different conclusions about the role nuclear will play in meeting climate goals. Nuclear power is dead. Long live nuclear power. Nuclear power is the only way forward. Nuclear power is a red herring. Nuclear power is too dangerous. Nuclear power is the safest power source around. Nuclear is nothing. Nuclear is everything. It is now generally agreed ...

  • Toasting Pop-Tarts cheap: How electricity may solve our energy woes

    We tend to talk about electricity in terms of its problems — it degrades the environment, costs too much and messes up scenic views. But the Manhattan Institute’s Peter Huber takes a different stand in his new report “The Million-Volt Answer to Oil.”Huber says electric power may be the cheap, efficient resource we seek to give America energy independence. He divides energy into two camps: ...

  • Overview of biomass and bioenergy sources in northern B.C.

    Ibrahim Karidio identified four groups of biomass sources: cellulosic materials from wood residues, agricultural crops, animal wastes, and municipal and industrial solid wastes. “B.C. has a huge land mass,” Karidio said. Of the total provincial annual allowable cut, 47% comes from the Northern Interior. B.C. generates 31% of Canadian wood residues and 66% of Canadian surplus wood residues. ...

  • Mountain of Mulch Grows at Biomass Plant

    Renegy Holdings may not be in the mulch business, but you’d never know it. Piled on the company’s property is 25,000 tons of high-quality mulch, and that’s only since the beginning of 2009. By the end of the year, that pile is expected to triple in size to around 75,000 tons, with equal amounts expected to be generated in each of the next couple of years. “We’re technically not in the mulch ...

  • Is small business left out of the EE boom?

    The US has about 29.6 million small businesses and they employ over half of the nation’s private sector. They hire 40% of our high tech workers, make up 97.3% of our exporters, and generate most of our innovations, according to SCORE. http://www.score.org/small_biz_stats.html Still, we hear small business often say it gets the shaft when it comes to ...

  • Reality check: Is green arrogant?

    During a recent interview, a utility executive used the phrase “the arrogance of renewable energy.” He was talking about the need to keep costs in check and implying that green energy businesses do not.The executive asked that I not attach his name to the phrase. He was afraid he would anger those in the renewable energy world with whom he does business. Not so long ago, utilities publicly ...

  • What’s geothermal again?

    Some green energy sources seem to have charisma; others struggle for public attention with little success. Solar energy is an “it” technology, as evidenced once again by the tremendous participation in the annual Solar Power International conference in Anaheim, California this week (Oct. 27-29). Twice as many companies (945) are displaying their wares in the Expo Hall this year, despite the still ...

  • Googlifying the electric grid

    If you showed Alexander Graham Bell cell phone towers, he’d be stumped. But if you let Thomas Edison tinker with our electricity grid, he’d know just what to do — not because of his genius, but because electric transmission has changed little since Edison’s day. Telephone technology advanced; electricity did not. So says the Department of Energy. ...
