EDF Energy Innovation Series Feature #20: Renewable Energy Financing From Mosaic

By | Bio | Published: June 3, 2013

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.

Mosaic’s "crowd-investing" concept gives people the opportunity to invest in a clean, low-carbon energy economy

Over the last decade, web-based crowd funding has grown from a clever way for fans to fund their favorite artist to a multimillion dollar funding option for just about anyone with a new widget.  For as little as a few bucks, anyone can help a friend or stranger get a good idea to market, and you might even get one of the first CDs or gadgets that come off the line.

But crowdfunding isn’t really an investment.

Oakland-based Mosaic wants to do for renewable energy investing what crowdfunding sites have done for entrepreneurs. But rather than just offering a chance to help, Mosaic offers a piece of the profit.  Think of it as a renewable energy Kickstarter with a kickback.

"We connect individuals and institutions with high quality solar project investments," said Billy Parish, president and founder of Mosaic. "The fastest way to grow the clean energy economy is to allow more people to benefit from it." Read More »

Cream Cheese And Time-Of-Use Electricity Pricing

By | Bio | Published: May 7, 2013

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.

The Oil And Gas Industry’s Assault On Renewable Energy

By | Bio | Published: April 29, 2013

This commentary was originally posted on our EDF Voices blog.

Source: ali_pk/flickr

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.

Renewables BuyBack Bill Pays Good Money For Clean Energy

By | Published: April 15, 2013

Picture this: You live in Texas, the state with the most solar energy potential in the U.S.  Knowing this, you decide to install solar panels on your home’s rooftop because, in Texas, you can lease – rather than buy – the entire solar energy system.  The option to lease allows you to take advantage of a low monthly payment that will be offset by the savings on your energy bill, rather than face high upfront investment costs.

Now, while you are at work during the day, your panels are actually putting excess, unused energy back onto the grid, when electricity is most expensive.  And, that surplus of energy isn’t just wasted; it is used by your electric company to serve other customers.  In most states, electric companies buy this power back at a retail rate.  But, in Texas it’s not quite that simple.  In order to see any form of pay back, you have to be a lucky customer of one of only three retailers – TXU Energy, Reliant Energy and Green Mountain Energy – that offer “renewable buyback” rates in Texas.  If you happen to buy electricity from one of the other 50 retailers serving residential providers across the state, though, you could always switch over to a renewable buyback program.  But there is no guarantee that you will be paid a fair market value for the 25+ years your solar energy system is expected to last.

Making a long-term investment to protect against highly-fluctuating, unpredictable electric rates is a difficult decision, and making that decision without knowing whether you are guaranteed fair compensation is nearly impossible.  This is one of the key reasons why Texas lags behind the nation in solar adoption.  Fortunately, there is a solution in the works.  Senate Bill 1239 from state Senator Jose Rodriguez seeks to guarantee homeowners, schools and religious facilities at least a minimum buyback rate based on wholesale market energy prices, which were about 50 percent lower than retail rates in 2011, on average.  The bill has a similar impact for rural electric co-operative, municipal and independently-owned utility customers, ensuring that any homeowner, school or religious entity that installs a properly-sized solar energy system will be compensated comparable to the way a fossil fuel power plant is compensated in the wholesale market.

Lowering The Price Of Residential Solar Starts In The Neighborhood

By | Published: April 11, 2013

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).

Solar Market Needs New Investors To Continue Growth

By | Bio | Published: April 2, 2013

The recent headlines for solar power have been encouraging.  According to the Solar Energy Industries Association (SEIA), the cost to install solar is declining as panel prices fell by 41% in the fourth quarter of 2012 versus the previous year.  This helped US solar installations to grow by around 75% in 2012, from 1,855 megawatts (MW) in 2011 to 3,300 MW.  (For comparison, the average coal plant in the US has a capacity of about 650 MW).  Even better, they forecast that installations will continue to climb to an estimated 9,000 MW in 2016.

Unfortunately, lack of investment capital may be a barrier to realizing this vision.  If we do not have enough funding, these projects will never be built.  Bloomberg New Energy Finance forecasts that the industry will need $3.1 billion of equity investment in 2013, compared to $1.8 billion in 2012.  Environmental Defense Fund (EDF) is committed to helping expand the roster of investors in solar projects, as investing in these projects is often not only highly profitable but also a major contribution to the sustainability of our planet.

Large investors have developed two strategies to invest in solar projects.  The traditional method is to make investments in large, utility scale projects.  More recently, residential solar developers have created funds for investors to take stakes in a large number of residential and small commercial projects.  The latter strategy has made ‘no-money down’ solar available for homeowners who do not have the upfront capital to purchase solar systems, which can cost up to $15,000 or more.

Unfortunately, these investment strategies can be quite complex and are generally attractive only for corporations and certain wealthy individuals. To understand why, we need to explore the tax incentives for solar investors.  The federal government provides tax breaks for solar investors to accelerate deals, develop a robust market that is expected to lower costs over time and allow investors to capture part of the societal benefit of avoiding development of more fossil fuel power plants.  EDF believes that this is a very good idea.

Chasing Green: Going Solar By Paying Your Utility Bill

By | Bio | Published: March 22, 2013

This commentary was originally posted on our EDF Voices blog.

Source: SolarPowerForYou/Flickr

So far, my experience is that environmentalists and business executives often speak different languages. Take the basic idea of sustainability. To an environmentalist, sustainability, as applied to a business, refers to the amount of environmental damage it will cause over time. To a business person, the term refers to the ability of the business to generate profits and so sustain itself.

In other words, there is a profound difference between the "green" that environmentalists are focused on and the "green" that businesses must generate to survive.

At EDF, I am trying to bring those two camps together. Broadly defined, my work involves creating opportunities for companies to make profits by selling products that benefit the environment, usually by reducing carbon emissions. My belief is that, with the right incentives and market structures, the profit motive can be a powerful force for change. Green companies that hire workers also create new advocates for environmental policy.

A study by McKinsey, the big consulting outfit, has shown that there are potentially hundreds of billions of dollars in energy efficiency investments that could yield annual returns of 7% to 20%. At a time of historically low yields on fixed income investments, like bonds, those are pretty good numbers.

Mostly, I focus on increasing investment in energy efficiency and renewable generation projects for homes, offices and other commercial properties. In many cases we can lower a building’s utility bills, including financing costs, while also reducing carbon emissions.

Take investments in solar technologies. I am lucky enough to have pretty good credit and was able to get a solar installer to finance a rooftop installation that provided my wife and I with immediate savings. Unfortunately, many homeowners do not currently qualify for financing. So EDF is working to decrease financing costs and increase availability of capital for such projects through a program called On-Bill Repayment (“OBR”).

OBR can help a building owner finance, say, a rooftop solar array, with money put up by an third part investor, and then repay that loan through his or her monthly utility bill. The costs of the loan are reduced because the loan is part of the legally binding rate tariff for the property, and will remain in place even after a foreclosure.

Once we have OBR in place, far more homeowners should be able to finance the upfront cost of installing energy efficiency or solar projects that lower their bills. This creates jobs, saves money and is good for the planet. What’s not to like?

Take California. The state is expected to initiate an OBR program for commercial properties in about 4-6 months. EDF’s economists estimate that this program over the next 12 years will lead to about $7 billion in third-party clean energy investment, create 50,000 job-years that cannot be exported. Over the same period, OBR will the cut carbon emissions by 10.3 million tons, the equivalent to replacing 180,000 gasoline cars for 12 years with solar-powered electric vehicles. And the environmental benefit will continue to grow as we add residential customers and expand to other states.

OBR is just one way in which business and the environment can coexist. In future blog posts, I will look at other ways to achieve the same end.

Solar, Wind Prompting Electricity Grid Innovation In California

By | Bio | Published: March 4, 2013

In a February Wall Street Journal article (“California Girds for Electricity Woes”), reporter Rebecca Smith gives an alarmist and misleading account of California energy regulators’ efforts to secure a cleaner, less expensive, more reliable electricity grid.  Right now, California has plenty of power:  44 percent more generating capacity than it typically uses, including a considerable fossil fuel energy portfolio.  Renewables – large scale, rooftop solar, wind, and, increasingly, energy storage – make up almost 15 percent of the grid, a percentage that will more than double in the next decade.  These clean, innovative energy technologies are working to improve the system by reducing the need for fossil fuels.

The reality is that the grid is changing, driven by California’s quest to secure an environmentally safe and affordable electricity system. Increasing the amount of renewable energy on the grid will mean that more generation is variable; electricity output from solar and wind depends on sunshine or windiness, respectively.    Up to this point, California has met this challenge by backing up clean resources with fossil fuels.  But California’s ratepayers can’t afford to keep doing this, so instead of “girding for woe,” the CAISO and the CPUC met to proactively address our changing future – to move California towards cleaner, less expensive electric grid planning.

This new approach can increase California’s ability to rely on clean energy generation by building greater flexibility into the system – while giving more options to consumers.  Not only can customer-based (“demand-side”) clean energy technologies reduce reliance on polluting power plants, they are quite likely to be more reliable and are potentially more cost-effective.   Demand response, or the ability of customers to choose to save money by responding to a price or electronic signal from the grid operator in times of excess system demand, will be key to integrating large amounts of intermittent solar and wind without back-up fossil or storage.   In fact, during afternoon peak demand, where supply is extremely limited in its ability to serve load, the addition of virtual generation resulting from the participation of DR into the market will actually lower energy prices.

California has already installed a robust digital metering infrastructure – and it’s time to put these meters to work by enabling customers to participate in demand response and other demand-side programs.  Coupled with technologies that now allow for fast, reliable, automated ‘set-it-and-forget-it’ adjustments to electricity use, we can seamlessly integrate variable electricity resources, such as wind and solar, without disrupting energy users.  Customers can choose to become an energy resource instead of fossil fuel plants.  Read More »

El Paso Electric Inks Solar Deal That Is Cheaper Than Coal

By | Published: February 7, 2013

On the heels of our blog post last week, showing how competitive wind and solar power have become in recent years, is news of possibly the cheapest solar deal yet in the U.S. (that we know of publicly, at least).  Even more interesting is the fact that the deal was made between Texas-based El Paso Electric and First Solar, an Arizona-based solar manufacturer.  While it’s a little sad that a Texas-based company has to go to New Mexico to build solar, it’s at least heartening that they could partner with a U.S. company to get the project done.  First Solar has been one of the leading solar manufacturers for several years, and last year their suite of projects made them the #2 solar panel supplier in the world (up from #4.) 

Marty Howell, the City of El Paso’s Director of Economic Development and Sustainability, said that “El Paso Electric’s recent solar contract with First Solar is another example of our great partnership with El Paso Electric and how El Pasoans are working together to make our community more sustainable.”

This new 50 megawatt (MW) project in New Mexico comes in at 5.79¢/kilowatt hour (kWh), which is almost half the cost of a new “advanced” coal power plant (12-14¢/kWh), according to the Energy Information Administration.  It is helpful to note that the deal did benefit from subsidies, as detailed in an article by Renewable Energy World, including the Investment Tax Credit (ITC) – which provides renewable energy projects with a tax credit equal to roughly 30 percent of a project’s costs.  If we were to remove that credit and the benefit of local incentives, the project would come in right around the cost of a new advanced coal plant, even if the coal plant lacks carbon capture and storage technology.

Time will tell whether this deal is an exception or the new rule, but growing signs of price parity for solar power, and the continued growth of competitive wind energy, consistently point to a critical shift in our energy infrastructure.  With continued declines expected in both wind and solar prices, this First Solar project seems more likely to become the norm than not.  The only question is whether utilities and regulators are ready for such rapid growth in wind and solar power. 

In New Mexico, they certainly seem to be ready.  However, in many other states, including El Paso Electric’s home state of Texas, that’s still an open question.

Do We Need Breakthroughs Or A Simple “Carbon Diet?”

By | Bio | Published: January 29, 2013

Over the weekend, The New Republic published an interview with President Obama, where he noted the following: "On climate change, it's a daunting task. But we know what releases carbon into the atmosphere, and we have tools right now that would start scaling that back, although we'd still need some big technological breakthrough."  How accurate is the call for breakthroughs and what do we really need?

First, let’s look at where we don’t need breakthroughs, but instead more deployment – energy efficiency, of course, being Exhibit A.  Creative financing, such as on-bill repayment (OBR), at scale can speed up deployment here.  Similarly, unlocking clean energy to reduce carbon emissions from the electricity sector hinges on affordability.  Wind energy is already competitive with fossil fuels, in large part because the cost of wind energy has come down around 65 percent in the last 20 years, according to the National Renewable Energy Laboratory (yes, declining natural gas prices provide new competition, but EIA projects that natural gas prices will begin to increase in 2018, and wind power purchase agreements are signed for around 20 years at a fixed price).  Residential solar is verging on the tipping point for “grid parity,” or the point at which a source of power becomes cost competitive with other sources.  Bell Labs first introduced solar cells in the 1950s.  Environment California’s Research & Policy Center recently reported that they expect solar to reach grid parity in mid-2014 to 2016 at the outset. 

Of course, progress in lowering costs and increasing efficiency comes on the heels of many smaller innovations.  For example, innovations in materials science underlie many of the most promising technology evolutions, such as the role of carbon fiber as a basic raw material for wind turbine blades or the use of Gallium Arsenide wafers to reduce manufacturing costs for solar cells.  But, nonetheless, given our country’s strength in materials science (think of our leadership with companies like Dow, Dupont and 3M), such innovations seem imminently feasible and in my mind don’t require a major “breakthrough.” 

We’ve also delivered numerous hardware and software innovations to transform our electric grid into a more resilient, smart, “green” grid.  Even carbon capture and storage, to some a high stakes technology bet, is actually just a new configuration or application of engineering equipment we have installed and used for decades, such as heat exchangers, chillers, absorbers, pumps and compressors.

Where would I wave a wand for a breakthrough?  A cheap, reliable and efficient energy storage system wouldn’t hurt, one that replaces the clunky compressed air systems or the size limitations of batteries.  But, overall, the declining cost curves for clean energy solutions, due to innovations large and small, tell us an important story:  solving the climate crises is not unaffordable or necessarily a drag on our recovering economy as many fear.  It is certainly not infeasible nor hinging on that one great technological breakthrough. 

We need non-technological breakthroughs.  Like the new head of the World Bank, Dr. Jim Kim, who in Davos described wanting to make “everything the Bank does aligned with the effort to slow down climate change.”  And it is certainly cheaper than repeating the $50 billion recovery price tags that we might face time and again as Superstorm Sandy becomes the new normal. 

Americans love the quick technical fix.  But, today we have affordable answers right in front of us, it’s the willpower we may be lacking.  So, just as most of us believe that rather than wait for a dieting breakthrough, the best answer to weight loss is reduced consumption and more exercise – we need to go on a carbon diet.  Our economic and environmental health depend on it.
