High prices, infrastructure bottlenecks and climate change fears have all prompted New England to make a big switch to renewable energy sources. But what happens when our old-fashioned power grid has to make room for wind and solar? What are the consequences when this new clean energy system relies on fossil fuels to fill the gaps?
The Big Switch is a project of the New England News Collaborative, where we explore our energy system at a moment of big change. We'll look at energy storage and production, efforts at efficiency and conservation, current demands on the grid, and the battle over where to put the wind turbines, solar panels, and yes, the fossil fuel plants that keep our lights on.
Small electric utilities around Vermont are concerned their customers will face higher bills to pay for a boom in solar projects. Last month, the utilities complained to regulators about the subsidies they have to pay for certain solar projects.
A Nature Conservancy project in northern Vermont will store carbon to meet California’s greenhouse gas reduction goals. The group says proceeds from the sale of these “carbon credits” will pay for future land protection projects.
Energy analysts are seeing that, especially during heat waves like the one that’s gripped New England for much of the summer, BTM solar can actually have a big impact on our energy needs.
The owner of the Pilgrim nuclear power plant is selling it at a bargain price. In fact, it's practically giving away the plant and its $1 billion trust fund. But there's a catch.
Mary Hollis lives in a single-family home in Hartford. There’s a draft by the door where she eats breakfast. And during the winter, chills seep around pipes and through the front foyer.

Central Maine Power (CMP) and a group of stakeholders in the western region of Maine, where the company wants to build a major new transmission line, have strucka mitigation deal worth up to $22 million.
Solar power’s emergence as an important feature of New England’s energy landscape just hit an important milestone.
Right now, a group of hydroelectric dams on the Connecticut River are undergoing a once-in-a-generation process – a federal relicensing.
In the small town of Warren, Vermont a so-called “net zero” house is being built that will not use any fossil fuel. The house has solar panels on the roof to generate electricity and pipes in the ground to capture geothermal energy for heating. It won’t be using power from the grid that was generated with fossil fuel.
Massachusetts has announced their pick for the first industrial-sized offshore wind project: the Vineyard Wind project, which will build an 800-megawatt wind farm off of the southern coast of Martha’s Vineyard.
Electric vehicles, or EVs, make up a tiny fraction of the cars sold in New England. But new state policies — and a big cash infusion from the settlement of Volkswagen’s pollution scandal — could speed the building of electric vehicle charging stations and help push the regional market for EVs to new levels.
Massachusetts energy officials have announced they're going with Plan B to bring Canadian hydroelectric power to the Bay State. They've selected a back-up project that runs transmission lines through Maine, after New Hampshire state regulators refused to allow Plan A – the controversial Northern Pass project.
Massachusetts opted last week for one large power line to cover a big chunk of its energy needs for the next 20-plus years. The Northern Pass proposal beat out other big transmission projects and dozens of smaller options for the right to supply all renewable power the Commonwealth wants.
For the past eight years, New Bedford has been advocating for offshore wind and preparing their port to service offshore wind projects. But why is the city betting on this industry?
Eversource’s Northern Pass transmission line is the sole project picked for long-term energy contract negotiations with Massachusetts.
Connecticut's new budget will move tens of millions of dollars out of energy efficiency programs, sweeping that money, instead into the state's general fund.
For the last 10 years, scientists all over the world have been racing to figure out how to convert massive quantities of seaweed into biofuel. UConn Professor Charles Yarish is one of them.
New research from the University of New Hampshire says the greenest way to heat your home this winter is a wood pellet stove.
Massachusetts will select bidders to supply thousands of megawatts of renewable, carbon-free electricity.
New Jersey's Governor-elect Phil Murphy has vowed to "immediately" bring his state back into the Regional Greenhouse Gas Initiative, or RGGI.
New England electricity consumers paid billions of dollars more than necessary over a three-year period.
As my tour guide, Bill Eccleston, and I walked through the dirt, twigs and puddles of the George Washington Wildlife Management Area in Burrillville, we heard a bird call above us.
A new type of energy-efficient construction is drawing attention in the U.S. It’s called “passive housing” -- residences built to achieve ultra-low energy use. It’s so efficient that developers can eliminate central heating systems altogether. Imported from Germany, it's been a boutique building style until recently, with eco-minded home owners making costly upfront investments to downsize their carbon footprints. But now, New England is joining a surge in large-scale passive housing development.
As Kevin Sullivan slowly rumbles his pickup truck across his 60 acres of property near the Connecticut-Massachusetts border, he leans in and asks a question: What’s farmland?
After years of encouraging solar development, Vermont seems to be attracting the attention of national solar companies.
For more than half a century, a massive, oil-fired plant has been churning out electricity from an island in the heart of Maine’s Casco Bay, where sailors use its towering smokestack for navigation. The old generator is expensive to run and dirtier than new technologies, so these days it comes on only a few times a year. Nonetheless, since December, the wires on the island have been humming pretty much nonstop.
A play by Massachusetts to inject more renewable power into its electricity mix could reshape the entire region's energy landscape. Dozens of developers are competing to offer Massachusetts the best price for long-term contracts to supply clean energy to hundreds of thousands of homes.
The nation’s first offshore wind farm off the coast of Block Island is in the middle of its testing phase. It’ll start producing electricity next month. Delegates from various federal Sea Grant programs around the country got a boat tour of the turbines to learn how the Ocean State got this project done.
The nation’s first offshore wind farm off the coast of Block Island will start producing electricity any day now. It’s a pilot project that will change the way the people on this small island power their homes and businesses. They’ve relied on importing diesel fuel up to this point.
Has little Rhode Island become the center for offshore wind power in the United States? It sure seems like it. The nation’s first offshore wind farm will start operating off Block Island in November. The project drew interest from European visitors recently, and this week, Rhode Island hosted an offshore wind energy conference.
New England gets about half its energy from natural gas, a huge jump from a few years ago. But many environmentalists are pushing back on big investments in gas-fired plants, just as renewables like wind and solar are taking off. In Rhode Island, we look at the controversy over whether to build another gas-fired plant in a small town.
We can't control when the sun shines and the wind blows. That means sometimes extra renewable energy gets dumped, or a wind plant is told to power down. One Vermont startup is hoping it can use a humble appliance in your basement -- your water heater -- as a storage device for extra electricity.
There are wind projects throughout New England, but Connecticut hasn’t joined the movement. The state doesn’t have a lot of wind or a lot of available space, and only recently lifted a ban on wind turbine projects. In Colebrook, Connecticut, we find out why it's such a challenge.
New England gets nearly 10 percent of its energy from renewable sources, with more on the way. But that change is posing challenges for the region’s electric grid -- like in Vermont, where solar power is booming, changing the landscape and transforming the way we buy, sell, and transmit electricity.
A major transformation in the way energy is made, delivered, and used is happening, and it’s disrupting the traditional business model of electric utility companies. That model includes building big infrastructure projects to transmit electricity. One startup company in Maine is averting the need to build a costly new transmission line.
