How Battery Technology and Crowd-Sourced Energy Can Save Our Aging Grid

By: Karin Rives

Not too long ago, making and selling your own electricity via rooftop solar was a novelty. Today, with 784,000 homes and businesses in the United States already on solar, such transactions are taking place every day in 44 states.

Now comes Bring Your Own Battery

In California, Electric Vehicles are the New DeLorean in ‘Back to the Future’

CARRAs any child of the ’80s knows, October 21, 2015 is “Back to the Future Day” – the day that the film’s protagonist, Marty McFly, travels to the future in his DeLorean. Though it would no doubt be useful to have access to flying cars (think of the traffic one could avoid), Californians are seeing increased access to something more practical: electric vehicles (EVs).

In order to meet the state’s greenhouse gas (GHG) reduction goals, emissions from transportation – the sector most responsible for harmful pollution – need to be addressed. Enter Governor Brown’s zero-emission vehicle (ZEV) mandate, which aims to build enough infrastructure statewide to support one million clean vehicles by 2020, and put 1.5 million ZEVs on the road by 2025. With this executive order, we have a much better chance of ensuring a low-carbon future and effectively combatting climate change in California. Read More »

Cracking the Code on California’s Clean Tech Leadership

Clean Tech IndexBy: Katie Hsia-Kiung

It may be hard to believe that just 15 years ago the term “clean tech” was largely unheard of. Today, the term has gained widespread usage, and is often applied to a diverse array of businesses, practices, and tools. Clean tech not only includes renewable energy technologies like wind and solar, but also electric motors, green chemistry, sustainable water management, and waste disposal technologies, to name just a few.

One research institution that has followed this sector through its short, but burgeoning history, is Clean Edge, a firm devoted exclusively to the study of the clean tech sector. Last week, the firm released their annual U.S. Clean Tech Leadership Index, which ranks each state based on several indicators across three categories: technology, policy, and capital. For the sixth year in a row, California came out on top as the leading state for clean technology. In fact, over the past year, California has widened its lead over the rest of the pack, with a score that is 15 percentage points higher than Massachusetts, the state in second place. According to the report, “with 55,000 people employed in its booming solar industry alone, a carbon market in place with its AB 32 trading scheme, and a 50 percent renewables goal by 2030 set by Governor Jerry Brown, California sets the pace for what a clean-energy economy looks like.” Read More »

So You Want an EV? We’re Helping to Figure Out How to Make it Happen

Ride_and_Drive_EVs_Plug'n_Drive_OntarioYou may have noticed:  we’re big fans of electric vehicles (EVs) here at Environmental Defense Fund (EDF). Standard transportation fuels are one of the biggest sources of harmful greenhouse gas emissions, so vehicle electrification is a crucial part of our clean energy future. But getting more EVs on the road is about more than just giving customers incentives to buy these types of vehicles. We also need to deal with where and how we charge EVs.

From April 27th to May 4th, EDF was engaged in evidentiary hearings at the California Public Utilities Commission that dealt with San Diego Gas & Electric’s (SDG&E) new electric vehicle pilot. Representatives from EDF, the Utility Consumers’ Advocacy Network, the Office of Ratepayer Advocates, SDG&E, Pacific Gas & Electric, ChargePoint, KnGrid, the Natural Resources Defense Council, and the Green Power Institute, were all putting their best foot forward at the hearings. While there were sadly no Perry Mason moments (aside from an unsilenced cell phone playing the theme song in the middle of the hearings), I did try my hand at challenging witnesses on some key points through cross-examination for the first time. More importantly, the six-day-long process allowed Jamie Fine to shine as an expert witness and raise a number of matters of high priority to EDF.  Read More »

Clearing the Air: L.A.’s Vision for Clean Transportation

By: Larissa Koehler and Jorge Madrid

3091482472_90f3126a9f_zThere’s something remarkable happening in the city of Los Angeles, you can feel it in the air – and it’s definitely not the country’s worst pollution or the record-breaking heat – it’s the winds of change. Los Angeles is in the process of reinventing itself from a dystopian vision of traffic jams and unbreathable air into an urban leader in sustainability.

Last week L.A. Mayor Eric Garcetti unveiled a bold new plan (pLAn) to revolutionize sustainability in Los Angeles, including taking a bite of the big enchilada responsible for the most air pollution that gets in our lungs and greenhouse gas pollution that causes climate change – the transportation sector. Mobile sources (think diesel trucks, trains, ships, aircraft, and cars) account for 90 percent of Southern California’s harmful air pollution. Statewide, the transportation sector is responsible for nearly 70 percent of smog-forming gases and 40 percent of the state’s climate change pollution every year.

While some progress has been made – the number of non-attainment days (days when an area doesn’t meet the federal air quality standard) has decreased dramatically since the 1990s and the Port of Los Angeles has reduced diesel particulate matter by 80 percent since 2005 – there are still huge clean air disparities. We know the dirtiest zip codes in L.A. are also the ones with a disproportionately large amount of low-income communities and people of color. We cannot run a victory lap on this issue until EVERYONE in L.A. can safely get around the city and breathe healthy air at the same time. Read More »

Plugging Away – San Diego’s Plan to “Charge” Toward a Cleaner Grid

Source: Flickr/Kazuhisa OTSUBOWe love electric vehicles (EVs) in California and we want that love to spread. Why? It isn’t because of the cool factor – though, believe me, EVs like the Tesla are undoubtedly cool. Instead, it’s because these cars can offer significant benefits to the environment, electric grid, and economy.

California policymakers feel the love: in March 2012, Governor Brown signed an Executive Order that put an ambitious – and important – goal in place to provide the infrastructure for up to 1 million zero-emission vehicles (ZEVs), which includes fuel cell powered vehicles along with plug-in hybrid and battery EVs, by 2020 and put 1.5 million ZEVs on the road by 2025.

Here are some of the potential benefits of electric vehicles:

  • Reduce harmful pollution. Because EVs don’t produce any emissions from the tailpipe when they are drawing on energy from their battery – unlike traditional gasoline-powered vehicles – they can greatly reduce the amount of harmful pollution from which California suffers. Targeting tailpipe emissions, the largest contributor to dangerous emissions, will help the state meet its greenhouse gas reduction targets and reduce harmful pollutants that are causing elevated levels of smog.
  • Integrate more renewable energy. By charging at times when renewable energy is abundant (i.e., during the day to take advantage of solar and late at night to soak up wind power), EVs can enable the grid to handle more clean energy resources while still maintaining reliability.
  • Avoid increasing use of fossil fuel resources. Because solar power becomes unavailable when the sun goes down, the grid sees a steep increase in the use of fossil fuel-powered energy before sunrise and after sunset. If EVs charge during the day and then draw upon that stored energy when renewable energy is unavailable it will reduce the need for fossil-fueled generators to provide energy during these times of the day.
  • Avoid costs to utilities and residents. Capitalizing on the ability of EVs to integrate more renewables onto the grid can offset the need for additional, expensive transmission and distribution infrastructure as energy needs increase over time. In addition, EVs present an attractive financial proposition – by reducing or eliminating the amount that drivers spend at the gas pump, those who purchase an EV can recover the upfront cost of the car in a matter of years.
