A Clean Energy Paradise In The Pacific

When people think Hawaiian paradise, usually beaches, sun and trade winds come to mind. The price of energy? Not so much.

The state actually has the highest electric rates in the nation, approximately 2 to 3 times higher than the average price on the mainland. Given these high rates and the relatively mild climate, it makes sense that Hawaii’s customers are among the lowest monthly consumers of electricity at 585 kWh per month. However, despite low energy use, Hawaii’s customers still have the highest electric bills in the nation, at a whopping $203 per month on average. That’s 20 percent higher than the next highest state’s average bill!

It’s appropriate, then, that the Aloha State is on the forefront of policy measures intended to lower energy bills by looking to energy efficiency and renewable energy. Hawaii’s sunny days, coupled with its extraordinarily high cost of electricity, make going solar a relatively attractive option. And, not to mention, a much cleaner option given that the state relies on petroleum to generate over 75 percent of its electricity. In fact, Hawaii ranks third in the nation for total installed solar electric capacity per capita. However, the upfront cost of installation remains a significant barrier to widespread adoption of clean energy technologies. Access to financing is limited to those with stellar credit, and there is little incentive for renters to pay for energy upgrades to properties they don’t own. In Hawaii, solutions that work for renters are especially important since over 40 percent of the state’s residents rent.

But all is not lost. On February 1st, the Hawaii Public Utilities Commission (PUC) delivered a blueprint of a promising on-bill program to help residents and small commercial customers — including renters — invest in cost-saving, clean energy projects. By allowing for repayment of private financing for energy efficiency and renewable projects on customers’ monthly utility bills, Hawaii would be the first-in-the-nation to offer a statewide residential and small commercial on-bill program. The program works for renters and property owners because the energy benefits and the repayment obligation transfer from tenant to tenant with the property, enabling customers to invest in projects that outlast their terms of occupancy.

New Study Expands Efforts to Understand Climate Implications of Methane Emissions

New supplies of natural gas are no doubt changing our energy landscape and, of all fossil fuels, natural gas appears to be a smarter choice because its carbon footprint is smaller when combusted than coal or oil. When talking about natural gas as part of a potential climate solution, though, it is important to recognize its unique position as either being a good or bad thing for global warming – depending upon the amount of uncombusted methane emissions that are released into the atmosphere.

No matter what market forces dictate for the future of gas, it’s EDF’s job to ensure that natural gas doesn’t become a detriment to public health or the environment. And, with respect to air quality and climate, getting better data on methane emissions is essential.

Methane can be emitted at various points across the natural gas system. Comprised mostly of methane, natural gas is a potent greenhouse gas. When it enters the atmosphere unburned, it has a higher warming potential than carbon dioxide, the principal contributor of man-made climate change. The more gas released, the more it undermines the climate benefits of using natural gas as compared to other fossil fuels. Yet there is no clear sense of how much and from where methane is leaking out from the system, as my colleague and Chief Scientist Steven Hamburg has explained here.

Over the last year EDF has been orchestrating a large-scale study of methane emissions with leading researchers in the field and industry to better understand the amount of methane emissions across the natural gas supply chain. To date the 30-month collaborative effort, with a $10 million overall budget, is bringing together almost 20 universities and research facilities and about 40 industry partners, collectively, in order to measure methane directly at potentially large emissions sources as gas moves from the formation underground to the wellhead and then on to the consumer.

Yesterday, the third part of EDF’s methane research study was announced, which focuses on the local distribution of natural gas (from city gate to customer meter) Read More »

Lowering The Price Of Residential Solar Starts In The Neighborhood

By: Guest Blogger Scott A Robinson, University of Texas at Austin – Energy Systems Transformation Group

The price of solar panels has been decreasing rapidly in recent years. This decrease in price has been reflected in residential markets, with installation numbers booming. However, the total costs of the system remain high enough to discourage mainstream adoption of the technology—even in places like Texas, which have abundant solar resources.

From a customer’s viewpoint, there are two components of the cost of a solar photovoltaics (PV) system. The first is the “sticker price” of the system: the price you pay out of pocket. The second is information cost:  the time you must spend researching the technology to understand if it would be a good investment overall. This is a more difficult task for PV technology than it is for a new phone, or even a new car. The complexity of assessing solar PV creates a cost barrier on top of the reported price of the system.

To better understand these costs to consumers, and what can be done to decrease them, Dr. Varun Rai and I looked at data from PV owners across the state of Texas. We wanted to better understand the drivers behind the length of time people spent researching solar PV before deciding to buy. Our paper describing the results of the research, “Effective Information Channels for Reducing Costs of Environmentally-friendly Technologies: Evidence from Residential PV Markets”, was published last month in Environmental Research Letters (ERL).

EDF Energy Innovation Series Feature #19: Energy Analytics From FirstFuel Software

EDF’s Energy Innovation Series highlights innovations across a broad range of energy categories, including smart grid and renewable energy technologies, energy efficiency financing and progressive utilities, to name a few. This Series helps illustrate that cost-effective, clean energy solutions are available now and imperative to lowering our dependence on fossil fuels.

Find more information on this featured innovation here.

Driving improvements in the built environment is extremely impactful because buildings emit more than a third of our country’s greenhouse gases. Furthermore, according to IBM, roughly 30 percent of building energy usage is wasted. From location to location, however, these changes are sometimes hard to prove beforehand or demonstrate quantitatively after changes or investments are made. As the need to comprehensively tackle energy inefficiency has increased, so has technology’s ability to identify and measure the impact that building upgrades (retrofits), operational shifts or basic behavior changes can make.

Companies like Lexington, Mass.-based FirstFuel Software (FirstFuel) are doing for energy information what Google has done for online search: using complex algorithms to help make simple, usable sense of the massive amounts of energy data being collected by smart meters and other energy management devices.  Needing only one-year of hourly meter data and an address, FirstFuel’s Remote Building Analytics platform screens entire building portfolios for high-potential opportunities, conducts deep building audits and tracks energy savings – without ever going onsite or installing connected devices.

Using hundreds of proprietary algorithms and external weather and Geographic Information Systems (GIS) mapping technology, FirstFuel can provide detailed insight into each facility’s energy use and lay out specific, actionable recommendations for improved efficiency.  “We call it a ‘zero-touch’ approach,” said FirstFuel Software CEO Swapnil Shah. “It’s a very simple and compelling value proposition for the customer.  No hardware and no on-site visits mean you can begin to achieve true scale.” Read More »

New York City’s Air Is Well On Its Way To Becoming Cleaner Than Ever

NYC Clean Heat is halfway to achieving its goal of reducing harmful heating oil soot pollution in New York City by 50 percent by the end of 2013.

The NYC Clean Heat program experienced tremendous growth in 2012. The Mayoral announcement in June 2012 marked the official transition from the pilot phase to full implementation of the NYC Clean Heat program, which aims to clean the air in New York City by helping buildings convert from highly-polluting No. 6 and No. 4 heating oils to the cleanest available fuels. The heating oils used in one percent of New York City buildings create more soot pollution than all the cars and trucks in the City combined – that’s why upgrading these buildings to cleaner heating fuel is the single largest step New Yorkers can take to solve local air pollution.

The goal of NYC Clean Heat is to cut heating oil soot pollution in half by the end of 2013. NYC’s Department of Health estimates that achieving this goal will result in over 120 lives saved each year and prevent hundreds of emergency room visits and hospitalizations for respiratory and cardiovascular conditions.

I’ve been a part of the NYC Clean Heat team for almost two years now, and I can tell you that I am floored by the progress we’ve made. For instance: 

  • By the end of 2012, over 1,200 boilers – well beyond the number of conversions the regulations required – have switched to natural gas or ultra-low sulfur No. 2 (some of the cleanest available fuels), and over 2,000 additional boilers in line to convert.
  • These 1,200 conversions have resulted in over 150 tons of reduction of soot pollution, or particulate matter (PM2.5), which is equivalent to removing over 800,000 light-duty passenger vehicles from the road for 1 year. That’s over 13 billion miles travelled!
  • NYC Clean Heat won the 2013 Citizen Budget Commission’s Award for Public Service Innovation.

Why is all of this important? Approximately 1,500 buildings still need to complete conversions in 2013. Also, roughly 2,000 permits for No. 6 oil are set to expire before March 2014, representing 232 tons of soot pollution. Because this week is National Public Health Week, we are more aware than ever of what reducing air pollution in New York City will mean. NOW is the time to take action. Read More »

More voices emerge in support of California’s Low Carbon Fuel Standard

In the past two weeks, California’s California Low Carbon Fuel Standard (LCFS) received a heavy dose of positive news: strong support from major companies to develop cleaner transportation fuel options and solid evidence to prove the standard is working.

On April 2nd, major business interests and non-profit organizations across the state filed four separate briefs supporting the LCFS in the state Appeals Court in Fresno. The briefs, filed in response to a letter from the court in February, say definitively that the LCFS is a necessary program for California because it creates a market signal for new, cleaner fuels and solutions that can grow California’s economy and improve air quality.

The impressive diversity of interests weighing in is a who’s-who list of energy giants, including the nation’s largest supplier of natural gas for vehicles (Clean Energy), a 108-year old utility with 15 million customers (Pacific Gas & Electric), a consortium of alternative diesel companies (National Biodiesel Board and the California Biodiesel Alliance), and a coalition of five environmental organizations.

Notable excerpts from the briefs include:

With the impetus of the LCFS, the biodiesel industry in California is poised to triple in the next few years with substantial investments and new jobs in many of California’s most economically disadvantaged areas.

The National Biodiesel Board/California Biodiesel Alliance

Companies with the potential to exceed this target… can sell credits to regulated entities who can’t…creating a strong financial incentive for lower-carbon fuel innovation.

This is why the LCFS is so important- it provides a long term investment signal to create a robust alternative fuel market in a reasonable timeframe.

Clean Energy

PG&E supports the California Air Resources Board (CARB) in its efforts to preserve the LCFS…the LCFS is an important part of the overall California strategy to reduce greenhouse gas emissions, contributing 16 million metric tons of reductions…with a significant disruption to the LCFS program, it will make it less likely that California will reach its GHG emission reductions goals.

Pacific Gas & Electric

The LCFS encourages companies to invest in low-carbon fuels to meet increasingly stringent performance targets. Based on statements from alternative fueling industries and the CARB LCFS Fourth Quarterly 2012 Update, even at this early stage of implementation, the LCFS has resulted in rising quantities of lower carbon fuels being consumed in California and the market is rewarding investments in cutting edge, low-carbon fuels.

NGO Coalition that includes American Lung Association, Coalition for Clean Air, Conservation Law Foundation, EDF, and the Sierra Club

 

In addition to the legal filings, California also released its latest progress report on LCFS implementationin March showing growth in low carbon fuel deliveries to the state. Credits from the cleanest biofuels have grown by 300% in just nine months, and the data shows that regulated companies have over-complied with the standard by 45% — that’s more than a million tons over the past two years.

Reports have also begun surfacing that major deals for bulk volumes of low carbon fuels are on the horizon. For example, Neste Oil submitted a letter to the California State Senate stating they have already delivered commercial volumes of renewable diesel from tallow (an ultra-low carbon fuel) to California and “expects to deliver approximately a hundred million gallons of NExBTL renewable diesel fuel into California this year.”

In a similar story, San Diego-based Sapphire Energy recently entered into its first commercial agreement for “green crude” (made from algae) sales – an agreement with oil giant Tesoro. According to Sapphire’s president, “This moment is enormously important for the industry as it validates the benefits and advantages of [our] crude, and confirms its place as a market-viable, refiner-ready, renewable crude oil solution.” In a story on Sapphire’s website, the new partnership with Tesoro was described as potentially helping supply clean energy to meet the demand created by new fuel standards, including California’s Low Carbon Fuel Standard.

Implementation of the LCFS is still in the early stages, but in just over two years the standard has started to deliver tangible economic and environmental benefits. The regulation is poised to change a fossil-fuel dependent transportation system that has been developed over the last one hundred years and that costs California drivers almost one hundred billion dollars every year – most of which leaves our state (and nation) the moment it’s spent.

Using Californian ingenuity and the American entrepreneurial engine, we can change the status quo – toward a more sustainable system that doesn’t poison the air and pinch our pocketbooks.
