The article on offshore drilling is particularly relevant these days with Obama announcing plans to expand offshore drilling – and then a month later, the most disastrous oil spill possibly ever occurring in the Gulf of Mexico.

Offshore Drilling: Worth the Oil, or False Hope?
With fuel prices and consumption dominating the news—not to mention our country’s future energy policy—we offer a quick primer on the complex subject of offshore drilling. How much oil do we currently produce from offshore drilling, and how much might we potentially recover? What’s the status of the moratorium banning offshore drilling in various areas? What are the environmental risks? And perhaps most importantly, what is the psychological impact of thinking that offshore oil holds promise as a source of abundant, less-expensive oil when nothing could be farther from the truth?

Offshore Drilling: Background Info
The term offshore drilling refers to the extracting of oil from fields that lie beneath the ocean floor, anywhere from a few hundred feet to 200 miles off the coast. The first offshore well was drilled in 1887 from a wooden wharf off Summerland, California; technology improvements have made it possible to drill in deeper water and farther from shore ever since. Today, some 4,000 platforms operate in the U.S. federal waters in the Gulf of Mexico, primarily off the coastlines of Louisiana and Texas, and off the coast of Alaska, producing approximately 565 million barrels of oil per year, according to the U.S. Energy Information Administration’s overview of offshore activity. U.S. offshore oil production of 565 million barrels per year equates to roughly 1.5 million barrels per day; contrast that figure with U.S. current oil consumption of 21 million barrels per day.

Offshore Drilling: What’s the Fuss
The debate about offshore drilling stems from questions over how much oil potentially could be recovered from underwater fields versus the time and cost, both in dollars and environmental impact, related to that process. Common misperceptions notwithstanding, the debate does NOT stem from notions that offshore drilling could eliminate U.S. need for foreign oil (at current consumption, the U.S. uses 8 billion barrels of oil per year; conventionally recoverable oil from offshore drilling is thought to be 18 billion barrels total ever—not per year). The debate does NOT stem from notions that offshore drilling would guarantee lower fuel prices (oil is a global commodity, and U.S. production is not big enough to influence global prices).

Offshore Drilling: Environmental Risks
Environmental risks associated with offshore drilling include discharges or spills of toxic materials, interference with marine life, damage to coastal habitats, and effects on the economic base of coastal communities. Recent research suggests that transporting the oil poses greater threats than the drilling process itself. In Louisiana, the 10,000 miles of canals dug to transport oil and lay pipelines contribute to coastal erosion because the canals crisscross the state’s coastal wetlands. While technology improvements have lessened the occurrence of oil spills in the last 40 years, the Minerals Management Service, a bureau in the U.S. Department of the Interior that manages the nation’s natural gas, oil and other mineral resources on the outer continental shelf, projects about one oil spill per year of at least 1,000 barrels in the Gulf of Mexico over the next 40 years. Every three to four years, it says, a spill of at least 10,000 barrels can be expected. Those spills could potentially hit the beaches of western Florida, Alabama, Louisiana, and Texas.

Offshore Drilling: The Moratorium
Rights to U.S. offshore areas are shared between the states and the federal government according to various acts passed over the years. Specifically, the states have jurisdiction over any natural resources within 3.45 miles of their coastline (except Texas and the west coast of Florida where the jurisdiction extends to 10.35 miles), and the U.S. has rights up to 200 miles off the coastline. Offshore drilling has been banned in various areas thought to be particularly environmentally sensitive over the years. An offshore oil moratorium that had been in effect since 1981 expired October 1, 2008. With the lifting of the ban, areas in the Gulf of Mexico can be opened up for drilling by the federal government. Additionally, areas off the coasts of California, Virginia, North Carolina, South Carolina and Georgia can be opened up if those states approve. According to an Nov. 12, 2008, MMS press release, the agency has already begun the process for approving leases off the coast of Virginia. However, offshore drilling in new areas won’t deliver a drop of oil for ten years, according to numbers cited by the Bush administration two years ago. In fact, the U.S. Energy Information Administration recently did a detailed study of the likely outcome of offshore drilling for their Annual Energy Outlook 2007, and concluded that increased access would not have a significant impact on domestic crude oil production or prices before 2030.

Offshore Drilling: False Hope
It’s too soon to tell what the real impact of the moratorium being lifted will be. But the psychological impact of knowing there is more oil available to be drilled may be a negative for Americans’ energy-mindedness. “Thinking that there is more oil to be drilled offshore gives people a false sense of hope that there’s actually enough oil out there to make us energy independent,” says Jonathan Dorn, staff researcher at the Earth Policy Institute. “Nothing could be farther from the truth. The DOE data shows that there’s an insignificant amount of proven oil reserves, plus it will take five or 10 years to drill the oil given the existing backlog in the offshore fleet and other factors.” A similar view is shared by Sierra Club executive director Carl Pope: “All the debate about drilling this year accomplished nothing other than serving as a distraction from real energy solutions. Every time Congress tries to implement real clean energy solutions, the oil industry and its allies demand a ransom. Once the politically-charged election season is over we will be able to revisit this issue as part of a comprehensive energy bill that moves us away from dependence on oil and invests in clean energy solutions.”

Offshore Drilling: Facts and Figures

  • Offshore drilling currently accounts for 30 percent of total U.S. oil production.
  • The United States currently produces approximately 1.5 millions barrels of oil per day from offshore drilling, and consumes nearly 21 million barrels of oil per day.
  • The United States currently consumes nearly 8 billion barrels of oil per year.
  • The Minerals Management Service estimated there were 76 billion barrels of “remaining undiscovered technically recoverable” oil in U.S. offshore regions, but this estimate represents the “potential hydrocarbons of an area that can be produced using current technology, without any consideration to economic feasibility.” Of this 76 billion barrels, 18 billion are considered “conventionally recoverable.” Source: U.S. Energy Information Administration Overview report.
  • One barrel equals 42 gallons of crude oil.
  • Of the crude oil consumed in the U.S., 66 percent is imported.
  • U.S. oil production currently occurs onshore in the lower 48 states (2.9 million barrels per day), offshore (1.4 million barrels per day primarily in the Gulf of Mexico, plus 0.7 million barrels per day off Alaska).
  • Lifting the moratoria on drilling in the Outer Continental Shelf (OCS) would reduce the price of a gallon of gasoline by at most a few cents—and this would not be seen for at least another decade.
  • Oil is traded as a global commodity and its price is set on the world market. The Organization of Petroleum Exporting Countries (OPEC) could simply reduce exports to negate even the nominal potential price reduction.

VOCs: Volatile Organic Compounds, Indoor Air Quality and Respiratory Health
You can’t see them, but they’re all around us. They aren’t listed as ingredients on the objects we bring in our home, but they’re often there. They’re volatile organic compounds, or VOCs, a wide range of carbon-based molecules (organic compounds) used in a wide range of products that find their way into our homes. Under normal conditions, they vaporize, effectively leaving their host and entering the air, where they combine with other airborne compounds to form ozone, which isn’t good to breathe.

The Environmental Protection Agency recently released a digestible report breaking down the science behind climate change. Here are some highlights from the report:

Worldwide greenhouse gas emissions have increased 26% from 1990 to 2005. Carbon dioxide emissions, responsible for 75% of total emissions, increased 31%.

This image speaks for itself. The extent of Arctic sea ice last year was 24% below the average from 1979-2000.

And here’s a visual representation on plant hardiness in the US and the trend moving northward, with zone 3 areas almost completely disappearing.

How green is your HDTV?

by Marcia on April 7, 2010
TAGGED WITH 

Finding the eco-friendly (or the least eco-hostile) TVs can still be tricky. Statistics on power consumption are available if you look for them (CNET maintains a helpful database), but they aren’t typically flaunted. Even when “eco-friendliness” is advertised, it might just be a case of subtle greenwashing. Vizio LCD TVs branded with the Eco HD tag, for example, are at least 20% more efficient than the latest Energy Star guidelines call for, but that’s still a far cry from being a true energy-sipper.

The Energy Star sticker is theoretically a good starting point in the search for a green TV. But as of March 16, more than 1,100 HDTVs are Energy Star 3.0 compliant. That’s way too many TVs for the designation to be meaningful. Thankfully the newest Energy Star standard (version 4.0) takes effect on May 1 and is much more discerning. For example, a 42-inch HDTV must be 45% more efficient to be compliant under the new standards.

Generally speaking the most environmentally friendly TVs are LED-backlit LCD sets (I’ll just call them LED TVs from here on out). They’re far more energy efficient than plasma or conventional LCD sets, which both use fluorescent lights. Fluorescent lamps release about 80% of their energy as heat, according to the Energy Star Web site, so a huge amount of power is wasted. A well-built LED is much more efficient and should be mostly cool to the touch.

LEDs are also free of mercury, a toxic metal used in all fluorescent lights. So when it’s time to pitch (or preferably, recycle) your LED TV, hopefully many years down the line, it’ll create less toxic waste than a conventional LCD or plasma.

Report: Spare-fridge trend undermines energy savings

by Marcia on

Many people who splurge on high-tech eco-friendly refrigerators are undermining their environmental efforts by continuing to use their old, inefficient fridges, according to a new study. A quarter of houses now have two refrigerators, the report found, and the rate is increasing by about one percentage point each year. “You’re not saving any money on efficiency if you’re keeping that old one plugged in,” warned one green-energy expert.

How to Help Stop Allergies and Asthma Attacks at Home

by Shana Fong on March 31, 2010
TAGGED WITH 

Respiratory allergies and asthma issues are very common, and both are made worse by breathing irritants in the air. However, it is possible to make sure the air you’re breathing at home is clean and free of the things that aggravate allergies and trigger asthma attacks.

Symptoms such as coughing and wheezing due to allergens or asthma triggers are a sign that your home is not healthy or performing well, especially if you’ve already taken measures such as getting rid of carpet.

The common culprit behind poor indoor air quality is dirty air being pulled into your home through an unsealed duct system or through other leakage areas. Since the duct system is usually in the crawlspace or attic, it can pull in outside pollutants (like ozone or pollen from outside or mold spores and dust from the attic) and trap them in your home. Sealing leaky ducts can often make a significant difference at home for people with allergies and asthma, but it is often overlooked as a solution. For the same reason, air sealing in the attic and crawlspace are also highly recommended.

It is also important to properly ventilate your home and clean/change your furnace filter regularly – or better yet, install a high efficiency air filtration system. If you take all of these steps, you can breathe easy knowing that the air in your home is healthy.

The Difference between Free and Paid Home Energy Audits

by Shana Fong on March 30, 2010

Here’s another question we hear from customers all the time:

What’s the difference between a free energy audit from a utility company like PG&E, and one that you pay for?

A home energy audit is the first step in understanding how to make your home more energy efficient by uncovering how it uses energy and where it is losing energy. You have a few options when it comes to energy audits:

Simple do-it-yourself audit: Utilizing a tool such as the ENERGY STAR Home Energy Yardstick, which compares your home’s energy use with others across the country and provides suggestions on improvements
Free audits offered by utilities, organizations, or companies: A basic assessment conducted by a technician that looks at some of the areas in your home that affect your energy usage and carbon footprint
Professional audits by home energy companies or raters: A comprehensive assessment performed by a certified auditor that identifies the most cost-effective improvements to address root causes of your concerns and provide long-term solutions

Both DIY and free energy audits are good starting points but vary greatly in process and goals from professional audits. Here’s an illustrative example of how they differ:

Acterra, a local nonprofit organization, offers free audits to homeowners in select areas of the South Bay. Conducted by a team of two trained volunteers over two and a half hours, the “HouseCall” is an introduction to basic energy efficiency and conservation measures. It includes simple upgrades such as changing out light bulbs to compact fluorescents, optimizing refrigerator and water heater temperatures, and installing faucet aerators. Additionally, the volunteers will suggest other tips on other energy-saving upgrades. For renters and homeowners alike, it’s a great first step if you are looking for a simple, no-cost way to reduce your energy usage by up to 10%.

Recurve’s energy audit includes a 20+ point inspection of your home, including blower door testing to assess the leakiness of your home, attic and crawlspace inspections, utility bill data analysis, heating and cooling load calculations (i.e. how much energy it takes to heat and cool your home on the coldest and hottest days of the year, respectively), lighting and appliance audits, and heating, cooling and water heating systems analyses. The result is a comprehensive report on how your home is currently using energy and a roadmap to making your home more healthy, comfortable and efficient. And if you move forward with the improvements, you will often see significant results – most of our customers see upwards of 30-50% in energy reductions.

In sum, free energy audits are a great way to identify easy, DIY fixes to your home and can be utilized by renters and homeowners alike. Professional audits offer a much more thorough look at how your home uses energy and the specific steps you can take to significantly improve efficiency in the most cost-effective path possible.

To clear a few questions/myths up:
• PG&E only offers free audits to businesses, not homes
• If you decide to do the energy upgrades, some professional companies will credit part or all of the audit cost back – making it essentially free
• Beware of free audits offered by companies that are just trying to lure in buyers of their product, instead of relying on a comprehensive whole-home approach

Remember, energy audits alone don’t save energy. Use the information you glean from your home audit to identify the improvements that make the most sense for your energy needs and your budget.

A recent study by energy efficiency nonprofit Home Performance Resource Center found that more than 90 percent of caulking and insulation, among other efficiency materials, is made in the United States. This is an example of another way energy efficiency retrofits support job creation – not only through installation, but manufacturing too.

Drafty House? New Windows May NOT be the Solution.

by Adam Winter on February 21, 2010
TAGGED WITH 

We hear this question from homeowners all the time:

I think I need to replace my windows because I can always feel a cold draft when I am next to them. Are there any alternatives, since it’s such a pricey upgrade?

Surprising to many, replacement windows are not always the best solution to cold drafts – particularly for homeowners on a tight budget. So before running out to the local window retailer, be sure to consider other possible causes for drafts and their (often times) less expensive solutions.

Typically, the cold feeling you get when standing by a window is caused by a combination of radiant heat loss as your home’s heat is drawn directly through the glass, and air leaks that allow cold outside air to flow through your home. Swapping single-pane windows with double-pane replacements will help with radiant heat loss, but if your house isn’t well sealed and insulated, investing in costly new windows might not solve the problem.

Draftiness is usually the result of warm air rising and escaping into your attic through leaks in walls, ceilings and can lights. As the warm air escapes, it is replaced by cold air that flows in from poorly sealed crawlspaces and other low-lying areas. That’s when you feel the drafts.

Finding and sealing air leaks can have a huge impact on interior comfort. The average home leaks 100 percent of its heated air every hour. At Recurve, we prefer leakage rates closer to 35 percent, which seriously reduces drafts and energy waste.

In most homes, windows only account for a small fraction of the air that leaks out. And because replacement windows are such a big investment, it’s usually more cost-effective to tighten your home first by improving insulation and sealing air leaks– particularly in the attic and crawlspace. Your home will also feel warmer if you close your blinds or drapes at night to reduce the amount of radiant heat loss.

In any case, it’s best to begin with a professional audit of your home’s energy performance. By conducting a thorough inspection of the various elements that contribute to your home’s overall comfort and energy consumption – including insulation, heating and cooling systems, and duct systems – the auditor can help you figure out which improvements will give you the most bang for your buck. You might find that $2,000 worth of insulation and air sealing will have the same impact as a $20,000 window upgrade.

If you have enough money left in your remodeling budget, energy-efficient replacement windows can be a terrific option. We’ve seen impressive results from a line of fiberglass windows manufactured by Sunnyvale-based SeriousWindows. Their top-of-the line windows achieve an insulation rating of R-11, which is better than what many people have in their walls and ceilings.

Finally, no matter what home energy improvements you decide to make, be sure to take advantage of the tax credits and other incentives that are available for this kind of work. An experienced energy retrofit contractor will be able to tell which incentives are available in your area, and even help you with the necessary paperwork.

Venture Funders Take Aim at Energy Waste

by Shana Fong on January 28, 2010

‘Energy efficiency to shine in 2010’ reports the San Jose Mercury News

A pair of articles in yesterday’s edition of the San Jose Mercury News shed light on the growing national interest in energy efficiency and on the proposed HOME STAR retrofit incentive program. “Solar and wind power may get the headlines and attention,” the newspaper reported, “but green-tech experts say 2010 will be dominated by energy efficiency, the mundane but critical process of cutting the amount of gas and electricity that homes and offices use.”

Of particular interest to business leaders in the construction and related manufacturing sectors is the fact that investors are increasingly betting on the profitability of reducing energy waste:

Venture capital investment in energy efficiency hit a record in 2009: at least 115 deals worth nearly $1 billion, according to a preliminary tally by the Cleantech Group and Deloitte. That’s up 39 percent from 2008. Meanwhile, solar, which had 84 deals worth about $1.2 billion, was down 64 percent from 2008, and there’s increasing talk about solar being “overfunded.”

“In 2009, there was a pullback and realization by investors that because of the capital intensity of solar, there may be safer places to put their money,” said Scott Smith, U.S. cleantech leader for Deloitte.”

Mercury News staff writer Dana Hull also emphasized the wider economic and environmental benefits of energy efficiency: “It’s increasingly seen as an effective way to create desperately needed jobs, save struggling consumers money, wean America from its dependence on foreign oil and reduce carbon emissions – all at the same time.”

A second article provides an overview of the HOME STAR incentive program:

Silicon Valley venture capitalist John Doerr, who serves on President Barack Obama’s board of outside economic advisers, is a leading champion for Home Star, which he describes as “Cash for Caulkers.” The idea has widespread support from big-box retailers, labor unions, environmental groups and the construction and contracting industries, which have been devastated by the collapse of the housing market. Although national unemployment remains at about 10 percent, almost a quarter of the nation’s construction workers are unemployed, according to the U.S. Bureau of Labor Statistics.

We are in an urgent moment where we desperately need jobs,” said Bracken Hendricks, a senior fellow at the Center for American Progress and an architect of the Home Star legislation. “You have business and environmental interests aligned around making this happen, and happen now. I have never seen a coalition this broad and this committed.”
