The explosion of green marketing claims: FTC jumps into the fray
Most people would agree that “green” sells. For example, according to the New York Times, consumers spent approximately US$54 million in 2007 on carbon credits to support tree planting, wind farms, solar power generation, and other projects intended to offset greenhouse gas emissions created by driving and flying activities. While there is broad agreement about the impact of green marketing, ...

A new EE resource: Distributed people
Energy efficiency is often described as the invisible resource. It improves our energy supply without any of the usual industry trappings: smokestacks, wind turbines, transmission lines and poles. This is one of its virtues.But efficiency’s invisibility also causes problems. Because it operates out of sight – inside walls, underneath lampshades, and in factory motors — efficiency tends to attract ...

Electricity use falls because of efficiency
Electricity sales can gauge the national economic health. An ailing economy uses less electricity because is produces fewer goods and services. Sometimes, however, electricity sales fall for a good reason – efficiency.Such is the case in the United States, according to a recent statistics released by the North American Electric Reliability Corporation (NERC). The organization annually assesses ...

The flawed economics of nuclear power
Over the last few years the nuclear industry has used concerns about climate change to argue for a nuclear revival. Although industry representatives may have convinced some political leaders that this is a good idea, there is little evidence of private capital investing in nuclear plants in competitive electricity markets. The reason is simple: nuclear power is uneconomical. In an excellent ...

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: ...

New energy economy emerging in the United States
As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States. The old energy economy, fueled by oil, coal, and natural gas, is being replaced by one powered by wind, solar, and geothermal energy. The transition is moving at a pace and on a scale that we could not have ...

EPA`s proposed underground injection control regulations
As the drivers for global climate change become better understood by scientists, politicians, industry, and the public, there is growing consensus that action should be taken to limit atmospheric emissions of carbon dioxide (CO2) and other greenhouse gases (GHGs). Even as wind, solar, nuclear, biofuels, and other alternative energy sources become increasingly important, the United States will ...

Drilling for oil is not the answer
The United States consumes nearly 21 million barrels of petroleum per day (7.5 billion barrels per year), one fourth the world total. Of the crude oil consumed in the U.S., 66 percent is imported. The U.S. is on pace to spend over $500 billion on petroleum imports in 2008. U.S. oil production currently occurs onshore in the lower 48 states (2.9 million barrels per day (mbd)), offshore (1.4 mbd, ...

Want a better way to power your car? It`s a breeze
Legendary Texas oilman T. Boone Pickens is half right. We do need to harness this country's wind resources for a homegrown source of electricity, as he has been urging this summer in expensive television ads. And we do need to reduce the $700 billion we may soon be paying annually for imported oil. But part two of Pickens's plan--to move natural gas out of electricity production and use it to ...

Congress feels no pain
A big question often asked by energy analysts is: How high must energy prices be to motivate customers to change their behavior? We are beginning to think that the more perplexing matter is just how much do we pay before Congress reforms its behavior.Prices are plenty high enough to encourage customers to conserve. Driving is down and pursuit of efficiency is up. Federal lawmakers, however, can’t ...

Mr. Pickens, what about plug-in hybrids?
T. Boone Pickens deserves kudos for his attention-grabbing television campaign aimed at helping America kick the oil habit. The billionaire energy fund manager can stop the most dedicated channel surfer mid-click when he proclaims that our spending on foreign oil could soon become the largest transfer of wealth in human history.Pickens’ plan has two parts. The first calls for more use of wind ...
