Clean Energy and Reducing GHGs

Nahua has goal of reaching 100% renewable energy by 2050. Get the big picture and learn how we're going to get there from City Energy Manager Doria Brown as she talks through Nashua's big climate goals for clean energy and reducing greenhouse gas emissions.

Powering Nashua with Hydropower

The energy we use to light, heat, and cool our homes and businesses comes from different sources. Some of these sources, like oil and natural gas, pollute our environment and are in limited supply. Clean, renewable energy, like the City-owned hydro dams generate pollution-free electricity for Nashua that is readily available. Nashua owns two hydro dams: Jackson Mills and Mine Falls.

Community Power

Community Power in Nashua

Community Power allows the City to use its buying power, as a collective, to purchase electricity on behalf of its residents in order to maintain low energy prices and gain control over where our energy comes from. Nashua residents are automatically enrolled in the Community Power Program. Check the rates and explore plans up to 100% renewable energy on the CPCNH site.

The Electrifying Benefits of Electrification

A typical single-family household in Nashua heated with gas will create about 182 metric tons of GHG emissions by 2050. If that same household was fully weatherized and running on a heat pump, however, those emissions drop to 30 metric tons. Every year that a homeowner delays action is a lost opportunity to significantly reduce emissions by electrifying their heating systems and installing high-efficiency heat pumps. Electric HVAC systems are also more energy efficient, can reduce costs, and improve indoor air quality.

Solar in Nashua

Powered by the Sun

Clean, renewable energy, like the privately-owned solar panels throughout Nashua, generate pollution-free electricity using a source that is in endless supply- the sun. Here we are looking at generation capacity – which is the maximum amount of electricity that could be produced by all of the solar panels in Nashua under perfect conditions.

UNIT

Kilowatts measure power. For example, the capacity of a solar panel. Kilowatt hours show the amount of energy generated or used in a given amount of time. For example, the amount of power a solar panel generated over a year or the amount of energy used by a building over a year.

Solar on Schools!

Big solar projects are on the horizon for Nashua's public schools as we turn empty roof space into an asset for generating clean energy. 

Teachers may not like smart phones in schools, but with the size of the solar project going in at Fairgrounds Middle School, you could charge over 69 million of them! Combined with the system on Dr Crisp Elementary, the schools will be producing the equivalent amount of energy as 140 single family households. Once the middle school is complete, Nashua will have 5 solar projects on our schools alone.
