Clay Mitchell from Revolution Energy surveys the 60 kW solar array at East Kingston Elementary school. Despite cold temperatures the week before, the panels give off enough heat that most of the snow has slide right off.
For the most dedicated environmentalists, small scale renewables, right in our back-yard are the gold standard of energy generation. In the final installment of this weeklong look at New Hampshire’s energy future, we consider what a more distributed grid might look like.
Along with smart-grid, micro-grid is the newest buzz word in the energy world. Basically it’s a little island of power lines coupled with its own source of energy, that is still wired into the broader grid. They’re not totally self-sufficient but can generate their own electricity for short bursts when needed.
This is SustainX's prototype of a 40 kW compressed air storage system in their facility in Seabrook. This machine has since been cannibalized to create a much larger 2 MW prototype. These machines can be used to smooth demand, either from renewables or for large electric users trying to save some money off peak energy rates.
The energy grid is vastly more complicated than it was ten years ago. The old model was to plug in and pay for what you use, but now the grid is starting to ask for something back from consumers. This change is aimed at flatten the demand curve.
Think about how you use electricity: you wake up, turn on some lights, and maybe have a hot shower. After work you come home, cook some dinner, and watch TV. In the winter, maybe you heat with some kind of electric heat, or – even more likely – maybe in the summer you switch on AC.
Hydro-Quebec generates a massive amount of electricity using hydro-power: 33,000 megawatts, which is more than the record peak of New England's electric demand. But the impacts from those dams are massive as well.
Along the corridor of towns that would host the controversial Northern Pass Transmission line, it’s hard to find much support for the project.
But with power plants retiring and the slow growth of many renewables, all of those rivers in Canada look mighty promising to grid operators. As part of our weeklong series on NH’s energy future we ask does big Canadian hydro have a place in New England’s energy mix?
New Hampshire’s energy grid relies heavily on fossil fuels like oil and coal, and getting the grid off of those fuels will be a major hurdle in addressing the challenge of global warming.
But here in New Hampshire, it’s proving a steep challenge to get carbon out of the electric supply, without breaking the bank for customers or utilities. But that doesn’t mean that people aren’t trying. As part of a weeklong look at New Hampshire’s Energy Future, we ask what’s being done about CO2?
