Chris Hogan A Smart Approach to Fuel Diversity Includes Nuclear

nationaljournalblog2 A Smart Approach to Fuel Diversity Includes Nuclear Earlier this week, Dave Parker participated in the National Journal’s Energy and Environment Experts blog to respond to their question, “Does Nuclear Fit The Bill?” His response is posted below and you can visit the National Journal Energy Experts blog to view the entire thread.

Fuel diversity in electricity generation is critical to the success of a sustainable grid, and nuclear power can and should play a key role in producing clean, baseload energy for the nation.  But the reality is that the last new nuclear reactor built in America was 32 years ago—in 1977—and today, despite having received applications for 26 new nuclear reactors, the Nuclear Regulatory Commission has yet to approve a single one, let alone the hundreds that would be needed to do the job that Sens.  Kerry and Boxer seem to envision.

The reasons are no secret—many in the environmental community consider nuclear power a danger to both the natural and man-made environment, even though nuclear power emits no carbon-dioxide or other greenhouse gas emissions, making it, from a global warming perspective, the most environmentally benign way to generate electricity.   It is also important to note that since the 1970s rapid advances in technology have made nuclear power far safer and more efficient—and the nuclear industry’s safety and security standards are the highest in the world.

The American Gas Association (AGA) believes that any climate change legislation should support the increased use of nuclear power as a way to enhance fuel diversity in the generation of electricity, while at the same time meeting our national goal of reducing greenhouse gas emissions.   Currently natural gas, the most environmentally friendly fossil fuel, is the fuel of choice in electricity generation.   Yet the best use of natural gas—meaning its most efficient and environmentally superior use— is directly in America’s homes and businesses.

AGA does not believe that natural gas should not be a part of the electricity generation mix.   Rather, we believe that increased fuel diversity, including the increased use of nuclear power, would allow more natural gas to be used directly in the residential and commercial market, where, for more than 40 years, natural gas customers have led the way in increasing energy efficiency and conservation.

Pam Lacey White House Missed the Boat on Energy Efficiency

Last week the White House released a new Executive Order that is intended to reduce the government’s carbon footprint and energy consumption. Great Goal!

In the early years of the plan, they got the carbon part right, which is fantastic. Federal agencies will set goals to reduce greenhouse gases emitted directly from federal buildings and activities PLUS emissions attributable to the electricity the government purchases from electric power plants.  That makes sense – if you want to reduce global warming, look at the big picture and figure out the real impact of your actions.

But in later years, they missed the boat entirely. After 2020, federal agencies will be required to design and operate “zero net energy buildings” – measuring energy efficiency only at the building site – using the same old “site energy” approach that has institutionalized energy inefficiency for decades.    It is time to look outside the box – literally!  The National Academy of Sciences (NAS), Natural Resources Defense Council (NRDC) and EPA Energy STAR have all rejected the old site energy approach and instead recommend using “source energy” to measure real energy efficiency and carbon output.

“Source energy represents the total amount of raw fuel that is required to operate the building. It incorporates all transmission, delivery and production losses, thereby enabling a complete assessment of energy efficiency in a building.”

The alternative method for evaluating building energy efficiency – known as “site energy” – looks only at the energy consumed on site, ignoring the energy wasted or lost in producing, generating and transporting that energy supply to the building. Based on a detailed analysis, EPA concludes that “source energy comparisons generally reflect energy costs and carbon emissions more accurately than site energy.

President Obama has made it a priority to move our country toward a new green economy in which we will reduce greenhouse gas emissions by using cleaner energy more efficiently.   And we agree wholeheartedly.  We will not achieve that goal, however, if the government continues to measure “energy efficiency” within the four corners of a building or appliance – ignoring the energy lost when coal or natural gas is converted to electricity at a power plant.

Today, on a national average basis, up to 70 percent of the available energy is lost in electricity, and only 30 percent is delivered to the end user. In contrast, less than 10 percent of available energy is lost during natural gas transmission and distribution; 90 percent of the energy in natural gas is delivered to the customer. Now that’s real energy efficiency.

Ignoring the energy inefficiency of purchased electricity makes no sense – especially in the context of solving global climate change. It does not matter if you reduce carbon emissions at a building site if the net effect is to increase overall carbon emissions somewhere else!   It’s not too late for the White House to catch that boat, but they need to get moving.

Lauren Blosse Natural Gas is the Cheaper, Greener Choice for Home Appliances, Analysis Shows

AGA has conducted an extensive analysis on the emissions and energy costs of home appliances, and the results are impressive.  We’ve found that the direct use of natural gas in residential appliances results in lower energy production, lower consumer energy bills and lower greenhouse gas emissions when pitted against fuel oil, electricity and propane.  The measurements were taken on a “full-fuel-cycle” basis, or, from the point of production to the end-use, accounting for energy lost along the way.  The full-fuel-cycle measurement is really the most logical way to measure energy efficiency and carbon output – otherwise consumers aren’t getting complete information.

Chris Hogan More on Kerry-Boxer: Worth The Wait?

Dave Parker participated in the National Journal’s Energy and Environment Experts blog to respond to their question, “Kerry-Boxer: Worth The Wait?” and he was asked to provide a follow-up comment. His follow-up is posted below and you can visit the National Journal Energy Experts blog to view the entire thread.

Senators Kerry and Graham’s recent opinion editorial, “Yes we Can (Pass Climate Change Legislation),” (October 11, 2009), and show of bipartisanship ignited thoughts that consensus on comprehensive climate change legislation this year might yet be possible. Admirable as that goal may be, we should not hold our breath.

Regardless of how likely or unlikely it is that Congress will pass climate change legislation this year or next, or the year after, one thing is clear – climate change and the challenges and opportunities it presents are real and will be with us for some time.

Fortunately, the same can be said of natural gas. Natural gas gets short shrift in the national debate on how to address climate change even though it’s the cleanest of all fossil fuels, containing just one carbon atom. It’s abundant – study after study shows the nation easily has a 100 year supply, and that number is likely to grow. It’s domestic – 97 percent of the gas we use is produced in North America. And it’s efficient – over the past 40 years, while the number of natural gas customers has doubled, actual gas use and greenhouse gas emissions have remained essentially flat.
