Cream Cheese And Time-Of-Use Electricity Pricing

This commentary was originally posted on EDF’s California Dream 2.0 blog.

“The cream cheese just fell off the roof of the car,” my 7-year old daughter said as I turned into my driveway after a trip to the grocery store. Right now you might be asking yourself, “What does this have to do with time-of-use pricing?” Allow me to explain.

We live in Alameda, CA, where plastic bags are prohibited and stores must charge for a paper bag. Alas, I had forgotten to bring a reusable one. To teach my children a lesson and avoid the public scorn (not so much the $0.05 per bag), I carried our groceries and asked the kids to lend their hands. And yes, I put the cream cheese on the roof of the car to free a hand to unlock it.

Once home, I realized that, in addition to almost losing my cream cheese, I’d been making potentially risky tradeoffs. After all, exiting the supermarket with full hands prevented me from holding my children’s hands while crossing a busy – and dangerous – parking lot.

Don’t get me wrong; I’m not lamenting the ban on plastic shopping bags. I think it makes perfect sense, but it takes time to start making the adjustment and the risk tradeoffs aren’t always obvious.

This scenario– making adjustments that may seem inconvenient and a bit scary, but are well worth the effort– plays out in other areas of life as well. Particularly in rethinking how Americans use and pay for electricity.

Most of us don’t think about how the time of day affects the cost of serving us power. In California, we aim to change that by moving to Time-of-Use (TOU) pricing – which will make electricity more expensive during times of peak, or high, energy demand and cheaper off-peak. In fact, just yesterday, the Sacramento Municipal Utility District (SMUD) recommended moving all residential customers to time-of-use rates by 2018 in an effort to give customers more control over energy costs.

EDF believes that TOU pricing will be best for people and the environment, just as banning plastic shopping bags effectively reduces their environmental impact. This approach can encourage conservation and reduce peak energy use while providing customers with more choices that can ultimately lower their monthly bills. Switching to TOU electricity pricing may feel to some like being thrust into a busy parking lot with an armload of groceries and two children to monitor. When should I use my dishwasher? Do I need to reset my air conditioner? Well, yes and no. You can choose to do nothing, or you can exercise a choice you don’t have with our current pricing structure: shifting energy use to times of lower electricity prices. It’s quite doable.

This Is Your Final Warning: Enforcement Needed To Curtail Continued Pollution Problems

Source: Chucker & Reibach

What makes you slow down more, a speeding ticket with a hefty fine or a warning? For most people, getting a ticket for violating the speed limit and having to fork over some cash to pay the fine is a powerful deterrent. In this case, enforcement has done its job. Giving you a penalty for not following the law makes you more careful in the future.

Air pollution rules are no different. Getting the rules right and then following up with strong, fair enforcement actions incentivizes industry to follow them, reduce pollution and clean up our air.

Since 2011, Wyoming environmental regulators have issued an annual study examining air emissions from numerous engines deployed in the state’s oil and gas fields. These engines power things such as compressors used to deliver natural gas to market.

It’s not surprising that the Wyoming Department of Environmental Quality (DEQ) has singled out these engines for special attention. A 2011 emission inventory for the Upper Green River Basin — a portion of the state that has struggled with ozone problems and is designated a nonattainment area by the U.S. Environmental Protection Agency for high pollution levels — found these engines to be by far the largest source of nitrogen oxide (NOx) emissions.

NOx is one of the two air pollutants that lead to harmful ozone, or smog, formation. In fact, the 2011 inventory indicates these engines emitted more than twice the NOx pollution of heaters, the next biggest source in the basin. They accounted for 1,639 of the 4,529 tons, or around 36 percent, of NOx emitted in the basin overall. Read More »

This Green Building Sets A High Bar For The Rest Of America

Source: Miller Hull Partnership

On Earth Day this year, The Bullitt Center opened its doors in Seattle, Washington.  The six-story building is being hailed as the greenest commercial building in the world.  Its specs are very impressive indeed, including:

  • 56,000-gallon cistern for rainwater collection;
  • Solar photovoltaic (PV) panels on the roof that are estimated to generate 230,000 kilowatt-hours per year;
  • Glass panels to showcase the engineering, including quick response codes to allow visitors to use their smartphones to find out more;
  • Real-time measurements of the building’s indoor air quality, energy conservation, PV production and water levels;
  • A mini-weather station that sends data to the building so that it can make adjustments to maximize tenant comfort and energy conservation; and
  • Measurement of energy use down to the individual socket.

The Bullitt Center aims to be certified through the Living Building Challenge, a rigorous set of standards that requires the building to meet complete water and energy self-sufficiency.  The Living Building Challenge has registered nearly 150 projects in 10 countries, but only three buildings have been certified in the US (in Missouri, New York and Hawaii).  It has been endorsed by the US Green Building Council (USGBC), originator of the Leadership in Energy and Environmental Design (LEED) standard, and is not meant to be a competition, rather a challenge to architects and engineers to aim even higher in their sustainable design efforts.

The Bullitt Center is a project of the Bullitt Foundation, and its leaders state that if the building is still the highest-performing office building in ten years, then they have failed.  They want to demonstrate that a building can be both self-sustaining and commercially viable and to serve as an example for others to learn and innovate beyond what they’ve done.

Clean Air Report Card: CO, WY Counties Get F’s Due To Oil And Gas Pollution

Source: Washington Business Journal

As a parent, I would not be pleased if my kids brought home F’s on their report cards.  Stern talks with my children, frantic phone calls and scheduled meetings with teachers and administrators would ensue.  Plans of action would be crafted.  It would be an urgent wake-up call.

This week, several counties in Colorado and Wyoming brought home poor grades on their clean air report cards.  The American Lung Association examined the levels of damaging ozone pollution in counties in these two western states and several of them are simply not making the grade.

High ozone levels are not new to Colorado.  Like many large metropolitan areas, Denver has struggled with ozone pollution (commonly known as smog) for many years. But historically, such problems have been limited to the summertime and to the Denver metropolitan area. Now unhealthy levels of ozone are becoming a common occurrence year-round and are emerging in rural parts of Colorado and Wyoming.

The culprit?  Air pollution from oil and gas development, which is just one of the environmental risks associated with a booming natural gas industry. Read More »

The Oil And Gas Industry’s Assault On Renewable Energy

This commentary was originally posted on our EDF Voices blog.

Renewable energy enjoyed a record year in 2012 – the U.S. wind industry surpassed 50,000 megawatts of electrical power generation capacity and solar proved once again to be the fastest growing energy source in the United States. That’s a milestone worth celebrating, since greater use of clean, homegrown energy resources creates jobs, cuts foreign oil imports, stabilizes prices, makes our system more resilient and reduces harmful pollution. The list of benefits is vast. So who could possibly be upset?

Well, some utilities that own old and often dirty fossil fuel power plants are upset that renewables are making it harder for their older, polluting units to stay in business. Then there are oil and gas industry association leaders like American Petroleum Institute (API) president Jack Gerard, who often talk about wanting a “level playing field” – implying that policies promoting renewable energy are unfair to fossil fuels.

Don’t be fooled. Renewable investments pale in comparison to the amount of money poured into fossil fuel companies since 1918 to fatten their bottom lines and crowd out competition. Fossil fuels have received around 75 times more subsidies than clean energy. Up to 2011 (adjusted for inflation), the oil and gas industry received $446.96 billion in cumulative energy subsidies from 1994 to 2009, whereas renewable energy sources received just $5.93 billion. An industry that has been enjoying federal tax subsidies for over a century has no standing to argue for a level playing field.

Heavily subsidized fossil fuels may have made sense 100 years ago, when we were racing to build the energy infrastructure of the last century. But today we’re racing to build the clean energy infrastructure of the new century — and we need to support a new set of industries. And we’re making real progress.

So it is no surprise that we are seeing a well-funded, industry-backed effort to roll back the policies that have been so successful in developing and deploying renewables. Take, for example, the latest assault on a series of state laws around the country that have increased the amount of clean, renewable energy these states produce.

Front Groups do the Dirty Work for Oil and Gas Industry

So far, 29 states have implemented Renewable Portfolio Standards (RPS) programs that require increased production of energy from renewable sources such as solar, wind, geothermal and biomass. They’ve been adopted in red states and blue – from California to Texas to Maine – through democratic processes and with popular support. RPS programs have helped jumpstart an industry that is spurring economic development, creating American jobs, boosting energy independence and cutting our carbon footprint.

A Bloomberg article released last week details how the oil and gas industry, through some self-described free market organizations that they fund, are trying to engineer a legislative massacre of these policies in more than a dozen states.

The groups may sound familiar: American Legislative Exchange Council (ALEC), which is currently pushing legislation around the country that would mandate the teaching of climate change denial in public school systems, and The Heartland Institute, which ran a billboard campaign last year comparing global warming “admitters” to Osama bin Laden and Charles Manson. Both have long opposed sensible energy policies. And their funders will sound familiar, too: the oil, gas and coal industries and their owners like the Koch Brothers.

Why The Texas Railroad Commission Must Get Well Integrity Right

On February 28, 2013, something went very wrong on a well site in Hemphill County, Texas:

According to Railroad Commission investigators, there was “one injury from well head being blown off when casing parted.”

According to the investigators, it took almost two weeks before this “frac water” stopped flowing out of the wellbore, and another week for the well to be plugged. The investigation did not determine the underlying cause of this accident.

Getting the rules right on well integrity is about preventing pollution, protecting the environment, securing property and, most importantly, saving lives. There were no fatalities in this accident, but sadly, that is not always the case (learn more about risks EDF’s natural gas work addresses).

The Railroad Commission is close to finalizing a historic well integrity rulemaking, the most significant overhaul of these practices in several decades. It is, on the whole, an excellent effort, bringing Texas back to the forefront on well construction, operation and maintenance practices. The proposals are progressive and will lead to real environmental benefit.

One particular provision of the proposal, however, falls short of the standard set by the rest of the rulemaking. It has to do with the amount of space surrounding casings, the steel pipes that go underground. This “annular space” (or “annular gap”) is supposed to be filled with cement as necessary to isolate groundwater from pollution, protect the casing from corrosion, and prevent gas from migrating to places it does not belong.

The width of the annular gap matters. In order for a cement job to be effective, the gap must be neither too wide nor too narrow.
