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 »

Energy Management Tools Boost Older Buildings’ Efficiency and Bottom Lines

CaptureBuildings use nearly 40 percent of all energy in the U.S. and account for a third of our greenhouse gases. Today, a growing number of commercial real estate leaders are looking for opportunities to upgrade what they’ve already got – rather than starting from scratch – to save money and lessen their environmental impact. These commercial real estate leaders know there is a great deal of potential in starting small, and in focusing on what best serves their bottom line.

Organizations that need a more tailored approach to making their real estate energy-efficient have a myriad of opportunities that are now being pioneered by property owners across the country. Leading companies are applying outside-the-box energy management solutions to buildings constructed before the green-building boom.

Here are two examples of companies that enlisted Environmental Defense Fund’s Climate Corps program to accelerate clean energy projects in their facilities and meet their corporate energy goals: Read More »

Oil and Gas Pollution Delivers a One-Two Punch to Our Public Health

One of the country’s largest leaks ever of natural gas, which is primarily made up of the potent greenhouse gas methane, has been going on in California’s Aliso Canyon for over a month. The volume that’s been leaking has been staggering—and the impacts to local residents severe enough to warrant relocating hundreds of families.

Major disasters like the one unfolding in Aliso Canyon have a tendency to grab our attention because the impacts are so acute and can be immediately documented—from the volume of methane that’s leaked (latest climate impacts estimate: equivalent to driving 160,000 cars/year) to the documented health impacts (bloody noses, headaches, breathing difficulties, nausea).

The Aliso Canyon leak, however, also provides us a good reminder of what communities across the U.S. who are close to oil and gas facilities have been increasingly concerned about—the ongoing environmental impact of air pollution that is being released into their neighborhoods, and the safety of those operations. Most of the pollution is invisible to the naked eye, but infrared cameras are bringing the problem into sharper focus, and with that a louder call for action and oversight by federal officials. EPA estimates that today, methane leaks from onshore oil and gas development is contributing climate impacts equivalent to driving nearly 130 million cars annually. And their emissions are contributing to unhealthy air for residents living next door and downwind of this development. Read More »

Local Solar Can Be Good For All Neighborhoods

Grid AlternativesSolar power in California has, in many ways, been an unparalleled success: the state has more solar power installed than the rest of the country combined. There are more solar workers in California (55,000) than working actors or utility workers. Solar workers earn a higher than average wage, and the industry is making strides in employing more women, veterans, and people of color. And, the median income of households installing solar in California in 2012 was between $40,000-$50,000, mostly middle- and working-class homeowners.

But there are two sides to this story because, unfortunately, solar power is still inaccessible to many low-income households.

Take my neighborhood of Boyle Heights, on the east side of Los Angeles, for example: over 70 percent of residents are renters and cannot install solar on roofs they don’t own. For those who do own their homes, many can’t afford to purchase their own solar system (the median income is just over $33,000) or don’t qualify for traditional financing. Residents here have captured a paltry $0.33 per capita in solar incentives over the past 15 years, as compared to Bel Air (yup, that Bel Air) which received almost $200 in solar incentives per capita – over 600 times more than Boyle Heights.

Driving the Last Spike: Linking California’s Electric Grid to Extend Clean Energy’s Reach

East_and_West_Shaking_hands_at_the_laying_of_last_rail_Union_Pacific_Railroad_-_Restoration“When the connection was finally made the Union Pacific and the Central Pacific engineers ran their engines up until their pilots touched. Then the engineers shook hands and had their pictures taken and each broke a bottle of champagne on the pilot of the other’s engine and had their picture taken again.” 

          –  Alexander Topence on the scene in Promontory,                   Utah in 1869 after Western governors drove the                    “last spike” of the Transcontinental Railroad.

These are good times for clean energy in California. A decade of visionary policymaking, a motivated private sector, and copious sunshine have joined together to reduce the cost of solar in the Golden State by 90 percent.

We already produce more solar energy than any other state. And thanks to a new law Governor Jerry Brown signed last month, SB 350 (De León), California has committed itself to yet another ambitious clean energy goal: 50 percent of electricity in the nation’s most populous state will come from renewables by 2030. Solar is a central part, among others, of California’s strategy to meet this new target.

Amid all this optimism, fast solar growth poses challenges as well. A lot of it has to do with timing. Read More »
