Energy Efficiency: A Resource For The Masses

This commentary was originally posted on the EDF Energy Exchange Blog.

By: Jessica Feingold, EDF Financial Policy Fellow

EDF believes that On-Bill Repayment (OBR) can do for efficiency what the third-party finance model has done for solar.

A recent post on efficiency.org, entitled ‘Solar is for the wealthy? Not anymore!’ highlights the growth of residential solar projects in middle-income markets (areas with median incomes of $50k-$100k) at the same time that financing became widely available from the private sector. While wealthier people have always been more likely to be able to afford the upfront costs of a solar installation, the introduction of solar leases and Power Purchase Agreements (PPAs) has extended the opportunity to a much wider range of consumers. This increase was described in detail in the 2012 California Solar Initiative Assessment. The success of solar among middle income households – achieved by eliminating upfront costs and allowing for monthly repayment through a solar lease or PPA structure – lends support to the notion that low-cost financing will be critical to making similar advancements in energy efficiency.

EDF has been working to create an OBR program in California that would provide financing for energy efficiency and renewable energy upgrades. OBR uses private capital to finance these clean energy upgrades at no upfront cost to consumers. However, OBR differs from the existing clean energy financing models in that it allows for repayment of a clean energy investment on the customer’s monthly utility bill. This reduces the administrative burden of an additional bill, while at the same time strengthening the credit of the loan by leveraging historically strong utility payment history. Thus, OBR would provide low-cost capital to consumers for clean energy upgrades.

Middle-income earners, in particular, stand to benefit from OBR, since they otherwise do not have access to low-cost, unsecured financing. Middle-income households are highly price-sensitive and likely do not have sufficient savings or home equity available to make clean energy investments that would reduce their utility bills, resource use and reliance on grid power. That is precisely why private sector financing was critical to promoting solar among middle-income households. Energy efficiency projects, on the other hand, have not yet attracted the low-cost private capital needed to achieve such widespread success.

OBR is an innovative financing solution that would allow middle-income households to realize the long-term benefits of energy efficiency, and provide more affordable financing for renewable energy projects as well.

Smart Meters Are Key To A Smart Grid

This commentary was originally posted on the EDF Energy Exchange Blog.

A well-designed smart grid is critical to the clean energy revolution we need – enabling significantly greater use of clean, renewable, domestic energy resources and improved air quality to protect the health of millions of Americans now harmed by dangerous air pollution.

Smart meters are a key component of the smart grid. They unlock air quality, climate pollution and public health benefits by enabling two-way, real-time communication that gives households, small businesses, manufacturers and farmers (and the utilities that serve them) the information they need to cut energy use and electricity costs. These devices help ensure that every day energy users reap the many benefits of the smart grid.

However, as a recent PBS NewsHour report explained, some activist groups and individuals in areas where smart meters have been deployed have expressed concerns over exposure to radio frequencies (RFs) resulting from the use of this technology. EDF supports further research and opt-out programs for those concerned. But what is missing from the PBS report is a clear account of the current, available scientific evidence on smart meters and health. EDF uses the best available science in all of its programs, and our smart grid initiative is no exception.

I am a member of EDF’s science team out of the San Francisco Bay Area and have dug deep into the peer-reviewed literature on health effects of smart meters, as well as independent assessments by agencies and industry groups and reports from government agencies. Here is what we know:

Research shows that every day humans come into contact with RFs from a wide variety of sources, including – but not limited to – wireless or cellular phones, microwaves, wireless internet routers, hair dryers, baby monitors and wireless laptops. Each has varying levels of exposure that depend on the technology and – importantly – on distance from the source.

One example in our daily lives is the use of a cell phone. A study by the Electric Power Research Institute (EPRI) found that during a call, cell phones held at the ear generate exposure levels between 1000-5000 microwatts per square centimeter (µW/cm2). In comparison, when transmitting, smart meters create exposure levels of approximately 8.8 µW/cm2. And that’s if a person is standing right in front of the meter. In homes and businesses, people are much farther away from their electric meter, so exposure levels are far lower. This means that a cell phone call exposes a person to hundreds of times more RFs than a transmitting smart meter. Moreover, smart meters only transmit signals roughly 2-5% of the day (approximately 30-70 minutes).

Source: CCST

The chart to the right (units in µW/cm2), from a report by the California Council on Science and Technology, puts smart meters in context with other RF emitting technologies. Keep in mind that this chart compares smart meters at a hypothetical maximum exposure level with transmission occurring during 100% of the day. Even at these hypothetical maximums, exposure from smart meters is significantly lower than other technologies already in use.

Assessments also show that impacts from RFs come in two forms, thermal (heat-related) and non-thermal. The Federal Communications Commission (FCC) sets safety standards for thermal impacts. Smart meter exposure levels fall well below the FCC’s limits for safety for thermal impacts. As for non-thermal impacts, the cumulative impacts of low-dose, long-term exposure are uncertain. To date, there is no scientific evidence of non-thermal impacts from smart meter RF emissions. EDF supports continued research on any possible health impacts of all RF emitters, but given the current standard for thermal impacts and uncertainties of non-thermal impacts, there is no evidence that the public would benefit from additional standards.

EDF’s number one priority is environmental and public health safety. We advocate for a “smart grid done right” to quote a message by EDF’s President Fred Krupp, and we are not alone in this effort. Though the PBS NewsHour story references “environmentalists” broadly opposed to a smarter grid, EDF is one of many environmental organizations strongly advocating for grid modernization as the clear path to lessening our dependence on fossil fuels and moving us toward a clean, healthy, low-carbon energy system. Our science team will continue thorough assessments of the best available science on this topic and our work with utilities, regulators and the smart grid industry to protect the environment and the health of customers.

Invest to Grow: EDF’s newest report highlights the opportunities created by the strategic investments behind California’s landmark emissions reduction program

Over the past 20 years, the unprecedented growth and resiliency of California’s clean and efficient economy has continued throughout economic recessions and budget crises – even while many other sectors of the economy have shrunk.  This growth has created a statewide infrastructure of companies providing the products and services that are at the heart of the transition towards a lower carbon economy envisioned by California’s landmark climate law.

Companies across the California landscape are now ready, willing and able to capitalize on opportunities to increase the efficiency of our state’s buildings, industries and transportation system.  The investments offered under California’s climate law will enable families, businesses and the government to spend less money on energy and fuel, resulting in dramatically reduced pollution. And, as documented in our new report, there is no limit to the benefits these investments can provide.

Invest to Grow tells the story of how investing emissions credit auction proceeds will move California’s clean economy forward, creating jobs and cutting pollution.  Investment opportunities profiled in the report include improvements in buildings and business operations, municipalities, transportation, schools, universities and hospitals.  These opportunities are supported by data drawn from state and federal government programs, industry led initiatives, and EDF’s own Climate Corps program.

By investing emissions credit proceeds in opportunities that decrease greenhouse gases, the state will keep California firms—from LED manufacturers and distributors to energy efficiency retrofitters—in the driver’s seat during the transition to a lower carbon economy.

That’s just another reason why recent misguided and inaccurate reports that California can’t afford to make these investments are so ludicrous. Not only can we afford to invest in California’s clean economy future now – these investments will pay dividends far into the future.

A Dynamic Approach To California Energy Use

Californians are poised for a more functional, data-driven model for setting the prices people pay for electricity. The new model will make the massive differences in costs of providing electricity during the course of a typical day more evident to us as energy users, thereby inspiring more efficient use of electricity resources.

The California Public Utilities Commission (CPUC) started a rulemaking to examine if the current rate structure for residential energy users is fair and equitable across customer classes and if it:

  • supports statewide-energy goals;
  • facilitating technologies that enable customers to better manage their usage and bills;
  • enables conservation and efficiency on the customer side of the meter; and
  • increases the reliance on non-fossil based generation to reduce overall greenhouse gas emissions.

We know already that the short answer is “no”, so CPUC is eyeing a transition to time variant (“dynamic”) rates. According to Pacific Gas & Electric (PG&E), with time variant, or what is often referred to as “time-of-use”, pricing – rates “will be higher during summer weekday afternoons when electric demand is higher, typically noon to 6 p.m., May through October. In return you’ll pay lower rates at all other times. This means that when you use energy is just as important as how much you use.”

EDF’s Energy team has been, and will continue to be, closely involved in the CPUC’s rulemaking, which will examine several facets of the current system. EDF has also been involved in the related smart grid proceedings, such as the deployment of smart grid infrastructure – which provides the ability to both measure energy use in real time and inform customers about the costs (and environmental impacts) of their choices to use electricity at different times of the day. This Advanced Metering Infrastructure (AMI) enables a smoother transition to dynamic rates for residential consumers.

EDF is very encouraged that the CPUC is considering time variant pricing because it will help consumers to be more thoughtful about their energy usage, particularly at times when demand is peaking and pushing electricity supply sources to their limits. This type of rate structure can encourage conservation and reduce peak demand while providing customers with more choices that can ultimately lower their monthly bills. For example, allowing consumers to see how much they can save on their electric bills by reducing their energy use during peak hours will encourage a shift of energy-intensive activities, such as washing and drying clothing and dishes, to off-peak (and less expensive) times of the day.

Because a dynamic pricing system will alleviate pressure on the electric grid during peak demand, it will also lead to a more stable, less expensive energy system that is increasingly resilient to extreme weather events. The economic motivation should also help to create an easy way for consumers to make decisions more efficiently, thereby lowering their electric bills and shrinking their environmental footprints.

Futhermore, dynamic pricing can help integrate renewables and electric vehicles into the electric grid by allowing utilities to respond to price signals more effectively. For example, time-of-use rates support electric vehicle charging at times when grid resources aren’t strained, such as late at night or early in the morning when most people are sleeping.

This new approach will facilitate conservation and energy efficiency, as well as an increase in the use of clean energy sources that avoid harmful greenhouse gas and urban air pollution. If adopted, the dynamic pricing model can be a common sense approach to saving energy and money, while promoting energy efficiency and a smarter, “greener,” electric grid country-wide.

California’s Coal Shadow Continues to Lighten Up – So Long, Reid Gardner

EDF first highlighted California’s coal shadow, which is the impact of coal-produced power sold into the state, in this 2005 report.  At that time, the global warming pollution emanating from these out-of-state smokestacks was equivalent to the emissions from more than 11 million cars, canceling out projected reductions from California’s landmark standards for motor vehicles and its 20% renewable portfolio standard.  

This week, the state Department of Water Resources  (DWR) took a huge step toward ending our coal shadow when it renewed its commitments to stop purchasing power from the Reid Gardner power plant in Nevada starting in 2013.  This critical step, the second major commitment in the past three months that will help California shed its demand for imported coal fired generation, is a strong signal that California global warming policies are working and that a full end of our coal shadow may be in sight. 

In July 1983, DWR entered into a 30 year contract with Reid Gardner to import up to 235 MW from one of the plant’s four units to power part of the State Water Project.  The project is the largest single consumer of electricity in California and pumps water up and down our state for residential, industrial and agricultural operations.  The coal-fired energy from Reid Gardner has accounted for 30-50% of DWR’s annual global warming pollution, while only accounting for 10-15% of the project’s overall energy supply.  This means that Reid Gardner is dirtier and less efficient than California’s other sources of energy. 

The Reid Gardner decision, coupled with the CPUC’s sale of their interest in Four Corners in March 2012, is a clear indication that California continues to stand at the forefront of environmental responsibility and seeks to protect its citizens from harmful pollution and reliance on inefficient energy development.  Our recently-enacted 33% renewable standard, the 2006 emissions performance standard for power plants, and the soon-to-be-launched cap-and-trade program for major polluters are but three of the landmark policies that are driving this fundamental shift toward cleaner sources of energy that will create jobs while improving air quality and protecting public health.

On-Bill Repayment: Two Big Developments in California

The California Public Utilities Commission (CPUC) recently released a Proposed Decision that included rulings on energy efficiency financing.  One ruling directs the state’s three largest utilities–PG&E, Southern California Edison and San Diego Gas & Electric–to develop an On-Bill Repayment (OBR) program for commercial properties that is based on a proposal developed by Environmental Defense Fund (EDF).

The Proposed Decision notes that the agency lacks the full necessary legal authority to implement an OBR program for residential customers. To address that, EDF is sponsoring legislation introduced by California Senator Kevin de Leon that would provide the CPUC with the necessary authority.

Senator de Leon and EDF have been working together to assemble a broad coalition of supporters including labor, contractors, building owners, banks and other investors, solar installers, energy efficiency project developers, environmental advocacy and environmental justice groups. 

We are excited to report that yesterday the bill passed the California Senate’s Energy, Utilities and Communications Committee. While we have a long way to go, this is another key step toward establishing a program that can invest billions of dollars of private capital in energy efficiency and renewable energy projects in California at no cost to taxpayers or ratepayers.

EDF will continue working with a broad range of stakeholders to successfully create the nation’s first statewide OBR program that is entirely financed by third parties. This landmark approach will enable project developers and building owners to use both conventional and innovative financing options to invest in energy efficiency and renewable energy projects.   

The CPUC is expected to vote on its proposed decision on May 10, 2012. The bill will continue being heard and voted on over the coming months. Once the final votes are in, California aims to have the commercial OBR program up and running by January 2013.

California sets pace on clean energy funding, patents and adoption, while cutting pollution

California continues setting the pace in the clean economy and is reaping tangible economic and environmental benefits from doing so. These are two of the key takeaways from a report released today by Next 10, which found that clean technology is fueling the state’s economic rebound and driving its efforts to cut climate pollution.

The 2012 California Green Innovation Index compiled by Collaborative Economics is the fourth annual report that tracks the “economic impacts of policies that help reduce state carbon emissions.” California’s Global Warming Solutions Act (AB 32) was among the policies cited as helping to drive the state’s economic growth.

According to the report, clean tech investments in California rose 24% between 2010 and 2011 to $3.5 billion. This represents 57% of all the venture capital (VC) funding in the country and 40% in the world. Additionally, California clean tech companies filed the most patents: 910 between 2008 and 2010. New York came in a distant second with companies filing 475.

Our solar industry did exceptionally well, attracting $1.2 billion, 62% of all U.S. VC funding in 2011. In part because of this investment, the Golden State reached a major milestone by installing 1,000 megawatts of solar capacity. Only five other countries in the world have hit this mark. Between January 1995 and January 2010, 1,503 solar businesses were founded here, an increase of 171%.

While this economic news is impressive, equally important were findings related to the environmental benefit: climate pollution fell even as the state's population was rapidly expanding. By 2009, for every dollar of gross domestic product (GDP), California was producing 28% less carbon emissions than it did in 1990. These reductions happened as the population grew by 8 million residents. Specifically, since 1990, California’s per capita GDP expanded 16% while carbon emissions per capita fell. This is particularly encouraging as California prepares to launch a carbon market that will limit overall pollution in the state to 1990 levels by 2020.

This latest report further demonstrates that environmental policies lead to economic growth. We wholeheartedly agree with Doug Henton, CEO of Collaborative Economics, who said that by “setting the market rather than chasing it,” California’s leadership is “paying off in the form of investment, innovation, and growth.”

New study confirms cap-and-trade leads to low-cost pollution reductions

After hearing that his obituary was published in the New York Journal, Mark Twain was quoted as saying, “The reports of my death are greatly exaggerated.” 

A similar retort applies to media coverage of a recently released report that questioned the effectiveness of cap-and-trade policy, since the study actually found that federal programs to control sulfur oxides (SOx) and nitrogen oxides (NOx) achieved goals at lower than expected costs. 

In the study, Lawrence Berkeley National Lab (LBNL) researcher Margaret Taylor found that greenhouse gas cap-and-trade programs do not necessarily induce the private sector to develop patents for innovative technologies to address climate change.  

Unfortunately for the study, the finding has been woefully misinterpreted and seized upon by those looking to undermine California’s plan to use cap-and-trade to cut climate pollution. David Roberts of Grist called the report’s announcement “a classic example of a press release overhyping and oversimplifying.” 

Published in the Proceedings of the National Academy of Sciences, the paper reaffirms the well-documented idea that cap-and-trade programs help companies meet emissions targets more cheaply than anticipated. The consequence, observed Taylor, was low allowance prices and a consequent decline in related patents.   

The key point of the paper though—and the main reason that this is a positive—is that cap-and-trade regulations keep pollution abatement costs low by encouraging program participants to find and adopt an unexpected range of approaches for reducing emissions.

Here are two key takeaways from Taylor’s paper:

  1. Reducing emissions more cheaply than expected goes hand-in-hand with faster-than-expected deployment of clean technologies and strategies.
  2. The flipside of low costs and rapid deployment means fewer new inventions and patents (a point Taylor emphasizes).

Overall, the report should be read as good news for California. As Taylor found, these approaches may not result in an onslaught of new patents but they are likely to cut pollution quickly and efficiently. Companies that are capped under California’s program can use industrial energy efficiency, building weatherization and fuel switching efforts to cut emissions.

We appreciate the spirit of Taylor’s inquiry. Yet, the question being asked isn’t the right one.  Rather than asking if a policy spurs measurable innovation in the face of climate change where action is unquestionably needed, the right question is, “does cap-and-trade show greater promise to spur low-cost solutions better than the alternatives?” 

The answer is a definitive “yes” when the cap-and-trade policy creates expectations of a nontrivial, persistent price on pollution. A recent story in Reuters stated that global warming is close to becoming irreversible if we don’t act now. California and economies around the world are acting by putting a price on carbon. This is the most environmentally and economically sensible approach to cutting emissions, which is key to helping us avoid the worst consequences of climate change.

Approved sale of Four Corners power plant shows California regulations are working

Today, the California Public Utilities Commission (CPUC) approved the sale of Southern California Edison’s (SCE) partial interest in the Four Corners coal-fired power plant to the Arizona Public Services Company. 

This sale is another indication that California’s landmark climate and energy laws—including: AB 32, which puts a price on carbon; SB 1368, its electricity performance standard; and SB 2, its 33% renewable portfolio standard—are working to encourage state utilities to find ways to move toward cleaner energy sources, cut pollution, protect ratepayers, and maintain reliability.

According to long-term resource plans and investment initiatives, SCE intends to replace the 800 MW of power that was generated near the Four Corners landmark in northwest New Mexico with lower-carbon resources such as natural gas, renewable energy, and energy efficiency – all of which can create in-state jobs and economic activity.  

Once the transaction is final, California will have dedicated contracts from four major coal-fired plants:

  1. Navajo (Arizona);
  2. Reid Gardner (Nevada);
  3. San Juan (New Mexico), and;
  4. Intermountain (Utah).

Of course, adherence to the California Environmental Quality Act and other applicable state and federal environmental standards must be observed in connection with investments or authorizations related to the sale of an emissions-generating source.  Such provisions are necessary to ensure that documented emissions reductions are real and achieve the environmental benefits desired. 

When this ownership transfer is complete, SCE’s contribution to California's coal shadow will drop by approximately 5 million tons of CO2 annually, an amount greater than the largest in-state source of greenhouse gas pollution. (EDF first highlighted California’s coal shadow, which is the impact of coal-produced power sold into the state, in a 2005 report.)

EDF looks forward to working with the CPUC and California utilities as environmental regulations are used to reduce our state’s future coal shadow.

Western region can gain million-plus jobs, grow GDP by $142 billion by accelerating move to clean economy

Speeding the development of clean energy in California, Oregon, Washington and British Columbia can generate more than one million jobs and $142 billion in gross domestic product (GDP) by 2020, according to a report released Tuesday.

It is the latest study showing that environmental policies can deliver broad economic benefits across industry sectors and to entire regions.

The report is a forward-looking assessment of how the West Coast mega-region can combine efforts to gain powerful competitive advantages. Among the key findings:

  • By 2020, the region’s clean economy could grow by more than 200% through the adoption of strategic policy measures, which represents up to $95.5 billion in new GDP contributions.
  • It is critical to put a price on carbon and use market-based approaches to drive innovation and investments that create long-term, sustainable employment.
  • The sectors with the highest job growth potential are: energy efficiency and green buildings; environmental protection and resource management; and clean transportation.

The West Coast Clean Economy Report was authored by GLOBE Advisors and The Center for Climate Strategies and released at the GLOBE 2012 Conference in Vancouver, Canada.
