Resiliency+: Renewable Energy Can Boost Grid Resilience in Vulnerable New Jersey

Resiliency+ is a new blog series, which highlights the ways in which different clean energy resources and technologies can play an important part in increasing energy resiliency in New Jersey and around the country.

BAPV_solar-facadeRenewable energy, such as solar and wind power, provides clean and sustainable power to our electricity grid. But it also offers other benefits beyond environmentally-friendly electricity. Renewable energy can increase energy resiliency by keeping the lights on, including at critical facilities in the wake of a natural disaster. That’s why it has the potential to play a particularly pivotal role in New Jersey, which is vulnerable to vicious storms such as Superstorm Sandy.

Renewable energy, unlike other forms of energy, is less vulnerable to sustained disruption. Other, more traditional forms of energy, such as fossil fuels, require an input (coal, oil and gas, etc.) that needs to be shipped, often via pipeline, to create electricity, leaving them vulnerable to a natural disaster that might interrupt transport. On the other hand, renewable energy has the ability to generate stable, on-site power from sources such as solar and wind when it operates from a microgrid. A microgrid can generate power both connected to and independently from the main, centralized grid. They can vary in size, providing power to several city blocks or to an individual home, but microgrids have the unique potential to “island” from the main electricity system. This is important during and/or in the wake of a natural disaster like Superstorm Sandy because this autonomous electricity system is able to power local buildings regardless of whether or not the main electric grid is down.

What it Takes to Compete in the Global Energy Race

cleanenergyraceAs the international sporting world shifts its sights from somewhat snowy Sochi (host of the 2014 Winter Olympics) to balmy Brazil (host of this summer’s soccer World Cup), a recent European Commission report shows that the European Union (E.U.) has its eyes fixed on taking the lead in another global contest of sorts: The race for a more competitive, secure, and sustainable energy economy. At stake are neither medals nor trophies, but long-term economic strength. As Europe – and, indeed, the rest of the world – play energy hardball, what does it mean for the global energy competitiveness of Team USA? Let’s look at the stats.

Current energy costs and competitiveness

Reliable, affordable energy powers industrial innovation and growth, making energy costs and policies one of the most important drivers of economic competitiveness.

Women in Power: Two Female Scientists Making a “Material” Difference in Clean Energy

WIPThis is the second in a series of posts about leading women in the power, environmental science, advocacy, policy, and business sectors. To see previous installments, please use the ‘Search’ field in the left sidebar to search for ‘Women in Power.’ 

Today, women earn roughly half of the bachelor’s degrees in the earth and biological sciences, but only about 20 percent of the degrees in physics and engineering. And as women’s careers continue to develop—through higher degrees and into professional positions—these numbers start small and only get smaller. Despite the tremendous educational and professional gains women have made in the past 50 years, progress has been uneven, and many scientific and engineering fields remain overwhelmingly male-dominated. The so-called “leaky pipeline” is a real issue. However, highly accomplished women in science and engineering do exist, and they are making huge differences in the way we make and manage clean energy.

I had the opportunity to sit down with two awe-inspiring female scientists who truly define “cutting edge” when it comes to the critical technologies we need to transition away from dirty fossil fuels. Dr. Stacey Bent, Professor of Engineering at Stanford University, and Dr. Angela Belcher, Professor of Biological Engineering at MIT, are both exploring the frontier of materials science, a critical area of study leading to advancements in renewable energy and energy storage.

Utilities Beware, Solar Power and Energy Storage Could be Coming for your Customers

The use of rechargeable batteries – in everything from iPhones, TV remotes, and even cars – has become pervasive over the past few years, especially as they have become more affordable. So why can’t we use them to help power our homes and businesses, too? The idea isn’t that complicated. But the cost of large-scale energy storage is still prohibitively high.

However, in select markets, like Hawaii’s commercial building market, privately connected battery storage is already cheap enough, compared to utility rates, to warrant installation. Furthermore, other energy storage markets, like California and New York, could reach the point of commercial viability in the next ten years – and not just for commercial buildings, but the residential market, too.

Demand Response: People, not New Power Plants, are Driving the Clean Energy Future

Clean energy resources, like wind, solar, and energy efficiency, have certain key advantages over traditional, fossil fuel-based resources: they don’t require expensive, polluting fuels or large capital investment, consume little to no water, generate negligible carbon emissions, and are easily scalable. To take full advantage of low-carbon, renewable energy sources, we need a power grid with enough flexibility to harness clean energy when it is available and abundant. That’s where demand response, a people-driven solution, comes in.

On a hot summer day, for example, electricity use rapidly increases as people turn on air conditioners to avoid the heat of the late afternoon. A decade ago, the grid operator’s only option is to turn on another fossil fuel power plant to meet the increased need for electricity. But, at any given time, there are thousands of light switches left on, idle water heaters, cycling swimming pool pumps, and forgotten thermostats that people could temporarily turn off or down, if only they were offered the right incentive. If asked, people can adjust their power usage in exchange for a financial reward. We call this “demand response,” and it is increasingly helping to balance the flow of electricity with our energy needs at a given moment.

Demand response diverts money that would generally go to a fossil fuel power plant to homeowners and businesses instead. In this scenario, a utility or demand response provider sends a message for participants to reduce electricity use at key times in exchange for a credit or rebate on their utility bill, in addition to the cost savings they will earn through conservation. Of course, participants always have the option to opt-out with the tap of a button on their smart phone or thermostat. Read More »

An In-Depth Look at the Future of American Energy and How We Get There

Imagine a world where homes not only run on clean electricity but also generate, store, and sell it. A world where power companies get paid for conserving energy, not just producing it. Where, when supplies are tight, the power grid gives customers the option of being paid to reduce and even shift their energy use to a different time of day, allowing us to use more renewable energy.

The U.S. is poised to spend around $2 trillion over the next two decades replacing our outdated electric infrastructure. We must make sure those investments are not spent on replacing old, dirty power plants with more of the same. If we’re truly going to unleash the clean energy future, we must invest in renewable energy and a smarter grid that can smooth out the demand for power and reduce harmful air pollution. Read More »
