How energy efficient is the Granite State? A new reports says not very, at least in terms of our buildings. Three years after Governor Lynch issued a Climate Action Plan, which included a call for more efficient homes and offices, UNH researchers find the state is way behind where it had hoped to be. We're examining what the problems are, as well as the prospects for future improvement.

A new report out from the New Hampshire Energy and Climate Collaborative finds that NH may not be doing enough to make homes more energy efficient.

Three years ago Governor John Lynch put forth his climate action plan, a roadmap for how to reduce the states carbon emissions. Number one on the list of strategies: maximize energy efficiency in buildings. But getting homeowners to invest in efficiency has been harder than policymakers had hoped.

The controversial mining method known as hydraulic fracturing, or "fracking", has led to a boom in production of cheap natural gas by getting at what was previously inaccessible pockets of gas contained in shale. Energy companies see it as way to reduce America’s dependence on oil and lower our energy bills, but concerns over environmental safety have others saying we need to slow down and study the issue. We cover all sides of fracking and its potential impacts here in New England.

Dear EarthTalk: Renewable energy production in the solar and wind markets currently receives about $7 billion in government subsidies annually, but is still not competitive against fossil fuels on a large scale. To what extent should the U.S. continue to prop up these industries as they compete against dirty energy?-- Jack Morgan, Richmond, VA


Headlines have quieted down on the Hydro-power project called Northern Pass, but efforts to continue and thwart the project are ongoing.  A new study questions the need for Northern Pass’s  hydropower, given low natural gas prices. Meanwhile, there’s been activity  on land purchases in the North Country that could connect the dots for the project’s final route. We will look at that latest news around Northern Pass.

Lawmakers in the New Hampshire House and Senate have agreed to try to reform RGGI – the region’s carbon cap-and-trade program – instead of trying to repeal it outright.

The bill that will go to the House and Senate for a final vote would only send around half of the RGGI fund money to energy efficiency programs. The rest would be rebated to electricity rate-payers.

Republican are working at finding common language on a bill that would weaken or repeal the Regional Greenhouse Gas Initiative, or RGGI. They will have to agree on a version that will get enough votes to overcome a governor’s veto.

The Environmental Protection Agency announced new rules Wednesday to control the problem of air pollution coming from wells being drilled by the booming oil and natural gas drilling industry.

Currently, waste products from the drilling operations, which include a mix of chemicals, sand and water, can be pumped into open enclosures or pits, where toxic substances can make their way into the air. The new rules will require this fluid to be captured by 2015, and flared — or burned off — in the meantime.

The GOP candidates for president have seized on high gas prices as a line of attack against President Obama, largely saying the answer is more domestic oil drilling.

But GOP front-runner Mitt Romney used to have a position seemingly at odds — at least in emphasis — with what he and the other Republicans are now advocating.

As Massachusetts governor, Romney said high gasoline prices "are probably here to stay," and he advocated policies to cut energy demand.

The rising cost of oil isn't just a hit to the family budget. Businesses are hurt, too. Few are more affected than firms like FedEx. It deploys nearly 700 planes and tens of thousands of trucks and vans every day to deliver packages around the world. And few business leaders are more focused on finding alternatives to petroleum-based fuels than FedEx CEO Fred Smith.

Shortly after Smith founded Federal Express, the 1973 Arab oil embargo almost killed it. The experience imprinted Smith with a keen interest in the price and availability of oil.

A house bill that would consider giving the Public Utilities Commission authority to force PSNH to sell its power plants to open up market competition is getting vocal opposition from business leaders and mayors in the state.

Berlin Mayor Paul Grenier says the move will raise electric rates and scare businesses away from his community.

The price of gasoline keeps rising for Americans, but it's not because of rising demand from consumers.

Since the first Arab oil embargo of the 1970s, the U.S. has struggled to quench a growing appetite for oil and gasoline. Now, that trend is changing.

"When you look at the U.S. oil market, you see that there's actually no growth," says Daniel Yergin, chairman of IHS Cambridge Energy Research Associates.

He says gasoline demand peaked in 2007 and has fallen each year since, even though the economy has begun to recover.

Rising gas prices have again shifted the political debate between those calling for more drilling to meet America's fossil fuel dependency and those advocating for investment in alternative energy sources. Many environmentalists are convinced that we are nearing the day when fossil fuels are tapped out, or too expensive or too harmful to extract.

Fuel Frustrations

Mar 16, 2012

The temperature isn't the only thing that seems to be rising lately in the Granite State, so are gas prices.  The cost of a gallon has gone up by about 20 cents in the last month and it shows no signs of slowing down.  Some are predicting that by the summer we may be paying upwards of 5 dollars for a gallon of gas.  Global energy markets blame harsh weather in Europe, tensions with Iran and a cutback in exports from such countries as Syria, Yemen and South Sudan.  Some suggest that higher gas prices may not only affect the average driver's wallet, but upcoming political races as well, as we

Shell Oil Co. has chosen a site near Pittsburgh for a major, multibillion-dollar petrochemical refinery that could provide a huge economic boost to the region.

Dan Carlson, Shell's general manager of new business development, said Thursday that the company signed a land option agreement with Horsehead Corp. to evaluate a site near Monaca, about 35 miles northwest of Pittsburgh.

Gasoline prices have risen about 50 cents a gallon since January. The national average for regular gas stands at just above $3.80 per gallon.

Pity the drivers on the West Coast. Prices there have been much higher. At a Chevron station in Culver City, Calif., the price on Tuesday was $4.45 a gallon.

"I do building maintenance," Ursula Matthews said as she filled her tank. "I do a lot of driving from place to place. It's hurting me. I cannot raise the prices [of my services] with the economy what it is."

Anti-Nuclear groups are angered by a decision of the Nuclear Regulatory Commission to exclude them from the re-licensing process for the Seabrook Nuclear Plant. 

A number of groups filed for intervener status so that they could file objections to the plant's extension of its operation to 2050. The coalition of environmental organizations planned to argue that renewable energy resources, such as wind power, could ultimately replace nuclear power. But the NRC ruled that their argument lacked merit, because that replacement power isn't available now.

Airplanes use a lot of energy to get from place to place, but they also create a lot of it - especially, say, when they're slowing down and landing. Engineers at the University of Lincoln are looking at how to harness that energy so airplanes can power themselves.

Economists say many industries are looking up this year. But perhaps none has a better outlook than the energy sector.

New drilling technologies and rising fuel prices have generated a boom in drilling — and lots of high-paying jobs for people with the skills to work in the oil patch. On some college campuses, companies are so eager to find petroleum engineers that they are offering jobs to students even before they have graduated.

The National Academy of Engineering in Washington, D.C., once asked its members to pick the greatest engineering achievement ever.

Their choice? The electrification of the country through what's known as "the grid."

Ernest Moniz, director of the Energy Institute at MIT, says they were right on the money.

"That reflects what an amazing machine this is, spread out geographically, always having to balance demand and supply because electricity is not stored," he says.

The mountain village of Kawauchi lies partly inside the area deemed unsafe because of high levels of radiation in Japan's Fukushima prefecture. Chiharu Kubota uses a high-pressure water gun to hose down buildings there.

Radiation is still leaking from the Fukushima Dai-ichi nuclear plant, which suffered multiple meltdowns immediately after last year's earthquake and tsunami.

'Nothing Is Better'

Rising gas prices have been the big energy story of the past several weeks. But many energy experts say that's a sideshow compared with the really big energy event — the huge boom in oil and natural gas production in the U.S. that could help the nation reach the elusive goal of energy independence.

Since the Arab oil embargo of 1973, energy independence has been a Holy Grail for virtually every American president from Richard Nixon to Jimmy Carter to Barack Obama.

But now, it might just be within reach.

Energy Fuels Newt Gingrich's Comeback Plan

Feb 26, 2012

When voters in Michigan go the polls Tuesday, it's unlikely many will tick the box for former House Speaker Newt Gingrich. In part, that's because Gingrich has all but written off the state, leaving his opponents to fight over it.

Gas isn't like a rare bottle of wine that fetches a high price just because it's rare. But at the same time, no one can agree what drives gas prices. Demand for gasoline in the U.S. is at its lowest point in more than a decade; domestic oil production is at an eight-year high.
