Belmont Citizens Forum Is it Time to Get Natural Gas Out of Belmont? Local initiatives could affect emissions, climate By Roger Wrubel In 2009, Town Meeting adopted a Belmont Climate Action resolution committing to an 80% reduction in our town’s greenhouse gas (GHG) emissions by 2050. An inventory in 2015 found that Belmont had reduced its GHG emissions by 5% compared with 2007. The inventory showed that the most of Belmont’s emissions came from home heating and vehicles. Most of the reduction in emissions in the last nine years is attributable to a shift from using oil for home heating to natural gas, and CLIMATE.NASA.GOV a similar shift to natural gas from coal Models of molecules of greenhouse gases that trap heat. and oil to generate electricity for the Natural gas is primarily methane.

In 2018, the Belmont Energy three sources, electrifying houses and businesses Committee issued Achieving Our Climate would drastically reduce our carbon emissions Action Plan: A Belmont Roadmap for Strategic and the rate of atmospheric warming.

The roadmap showed that For Belmont, the strategy involves moving the rate of decline of emissions in Belmont was to all-electric homes and transportation while not sufficient to meet our 80% reduction goal transitioning the electric grid to 100% clean by 2050. More aggressive action is needed. The energy. Toward this end, Belmont Light’s roadmap calls for “strategic electrification” with strategic plan calls for moving to 100% electric heat pumps replacing 50% of oil heating renewable energy by 2022. systems by 2025 and 50% of gas heating systems by 2032, and for 50% of all new vehicles to be Electric Heat Pumps electric by 2030.

But you can heat England temperatures, and removing heat your house and heat your water efficiently from inside a building for cooling.
