Power Plant Fuel Types, Emissions & Pollution Factors

On average, Connecticut citizens emit 1,978.9 kilograms of CO2 emissions from electricity consumption, which is the 45th worst per capita emissions rate for a state in the US. Total emissions from electricity consumption in the state is 7,175,892,118.73 kilograms a year, which is the 41st highest total amount of pollution for a state. Power plants in the state mainly use Natural Gas, which accounts for 26,101,635.18 megawatt hours (or 58.84%) of the fuel sources used for electricity generation in the state. Nuclear and Solar make up 35.98% and 1.28% of generation, respectively. There are 33 power plants in the state of Connecticut, which is the 33rd most plants in a state in the United States and translates to the 31st highest number of power plants per person.

Connecticut Net Metering

Approximately 53.33% of the electricity companies in Connecticut offer net metering to their consumers. The state has favorable net metering and feed in tariffs that make solar and other alternative types of electricity generation more realistic.

Energy Loss

The state has 6 companies who report energy loss. The average energy loss amount for these 6 suppliers is 1.24%. For comparison, the nationwide average energy loss is 2.43%. Connecticut ranks 4th best in the country for grid efficiency based on energy loss.

Solar Taxes And Rebates

In order to foster solar panel installs at private residences, all a state needs to do is pass legislation with tax and rebate incentives. Connecticut currently does not offer a state tax credit for solar panel installation at a private residence. Residents in the state enjoy rebates for private solar installs of over $500. This is the highest amount we've seen in the US. Connecticut citizens have the ability to apply a 100% property tax exemption for the installation of private solar, which is as good as it gets. Luckily, consumers in the state have a 100% sales tax exemption for the install of private solar at a home. This is as good as it gets.

State Level Initiatives

Customers searching for electricity options that use renewable sources will find it easier if there are state level legislation that encourage green energy usage. States that have Renewable Portfolio Standards (RPS) have requirements in place for all electricity suppliers who sell electricity in the state. These standards require that a percentage of electricity must be produced using renewable energy. Connecticut has made strong efforts to enact an RPS plan of action that requires at least 25% of electricity output to be fueled by renewable fuel sources. Furthermore, low income solar programs are another way a state can encourage renewable fuels and Connecticut is home to a program that does exactly that.
