Clean energy – not natural gas – drove decarbonization in 2017

Despite attempts by the Trump administration and the coal industry to limit clean energy in favor of fossil fuels – including a tariff on solar energy, a thinly-disguised bailout for coal and nuclear power plants (that was rightly rejected), and a dramatic proposed cut to energy research – we are accelerating the transition to a cleaner electric grid. In fact, last year was the first time the reduction in power sector emissions can be attributed more to energy conservation and renewable energy than switching from coal to natural gas.

The new 2018 Business Council for Sustainable Energy (BCSE) Factbook* highlights the electric power sector as the driving force behind the decarbonization of the U.S. economy. In total, power sector emissions declined 4.2 percent in 2017, mostly due to the 18.4 GW of new renewable energy we added to the grid (a 14 percent increase over the previous year’s total U.S. renewable capacity). In 2017, renewable generation represented about 18 percent of total U.S. generation (around10 percent from non-hydro renewables alone).

This explosive growth further cements renewable energy’s role in reducing emissions from the U.S. power sector. Let’s dig into the factors that led to this growth, and how we can extend this trend of emissions reductions from renewables beyond 2017. Read More »

Are electric vehicles finally taking off? Here’s what you need to know.

By Jason Mathers, supply chain director at EDF, Corporate Partnerships

Electric vehicles are poised to take off. We’ve just closed a year of record demand and investment. It’s no longer a question of whether electric vehicles – or EVs – will arrive, it’s how: How big of a role will EVs play, how soon and how clean will they be?

Popularizing EVs will depend on tackling key challenges. We’re seeing progress on several fronts.  Read More »

How electric trucks could disrupt highway transport and save businesses billions

By Jason Mathers, Supply Chain Director at EDF, Corporate Partnerships

Tesla’s much-anticipated electric semi-truck is garnering attention for its futuristic look and zero-emission promise – and it’s part of an innovation trend that is changing the future of trucking, with implications for entire supply chains.

United Parcel Service, Anheuser-Busch, Walmart, PepsiCo and J.B Hunt are among the companies rushing to secure orders of Tesla’s trucks, which are expected to be in production in 2019.

All-electric trucks can bring tangible benefits not just to truck owners, whose conventional vehicles can consume more than $60,000 worth of fuel a year, but also to their customers.

Fuel has long been a top cost for trucking, accounting for nearly 40 percent of the per-mile cost. Because fuel bills are passed on to companies that hire trucks to get their goods to market, electric trucks can thus promise businesses significantly lower and more stable operating costs.

For the business community as a whole, savings could be in the billions.  Read More »

Rooftop solar and EVs save water and cut pollution – and data can help us go further

Thanks to improvements in technology, it’s easier than ever to be green.

Solar panels and electric vehicles (EVs) are two prime examples of technologies that can help people minimize their environmental footprint, without sacrificing comfort or having to radically change their daily behavior. But the question still remains: How much of an environmental benefit do these technologies actually produce? And, are there actions that owners of these technologies can take to minimize their pollution footprint even more?

A new paper by my colleagues and me, recently published in Energy Economics, attempts to answer these two questions for households in Austin, Texas. These homes are part of Pecan Street Inc., a living smart-grid laboratory with the largest customer energy-use database on the planet. Using detailed household-level data from 2013-2015, we were able to track solar panel performance and EV use and charging patterns, and match these actions to two important environmental impacts: water use and greenhouse gas (GHG) emissions.

Our paper confirms that, in Texas, residential solar panels uses less water and pollutes the air less than using the central-grid power (based on its electricity sources during those years), and driving an EV instead of a gasoline vehicle generally reduces the household’s water and emission footprint, even though EVs charge from the grid. Moreover, our analysis demonstrates how carefully examining energy-use data can help us make sure we’re maximizing clean energy’s benefits. Read More »

A roadmap for a clean, modern grid – The 6 areas that should guide our efforts

Everyone has a role to play in fighting climate change. Farmers can use new methods to rotate their crops that keep more carbon safely in the ground. Consumers can act with their wallets – buying goods and services that produce less carbon than competitors. Our elected officials, of course, have a lot of influence in setting the narrative and enabling support for climate progress.

But around the country, in municipal buildings, state offices, and corporate headquarters, separate groups of people are busy designing and implementing changes that could have the biggest impact of all: a better, smarter, more modern grid.

Improving our electricity system could be the single largest climate fighting opportunity we have. But it’s not as simple as just putting solar panels on rooftops. Our grid was built over a century ago by different companies, cities, and co-ops. Pieces of it are owned and run by a dizzying web of stakeholders. Even if we could snap our fingers and spur all of these pieces to action, each player would manifest different versions of a “modern grid.”

Environmental Defense Fund (EDF) thus released a guide titled, “Grid Modernization: The foundation for climate change progress” [PDF], which outlines the six key categories that make up a sustainable grid modernization strategy. All of them are connected, either physically or digitally, or by legislation, regulation, or management. Most importantly, they’re connected by efficiency: If each of them is executed well, the whole grid modernization process will yield the best, most reliable, most affordable, and cleanest electricity system.

Here’s how New Jersey can capitalize on its best clean energy investment opportunities

Governor-elect Phil Murphy’s clean energy agenda has the potential to be a game-changer for New Jersey. His influence can position the state to regain its leadership in the fight against climate change, and create a clean energy economy that will lead to more jobs, and improve the health and well-being of all New Jerseyans.

To capitalize on this opportunity and achieve the state’s goals of clean, resilient, and affordable energy and transportation systems, we need to build on the progress we’ve made with new policies and programs that will allow the adoption of renewable energy technologies, energy efficiency, and clean transportation infrastructure at scale.

With New Jersey’s many competing investment needs, how will we pay for a much needed clean energy transformation? Public funds, whether from tax payers or utility customers, are not enough. EDF’s latest report, Financing New Jersey’s Clean Energy Economy: Pathways for Leadership, analyzes three innovative financial approaches that leverage public resources to catalyze private investment in these technologies.
