If you’re looking to take a step in your household with lots of impact, this is it. Electricity generated from fossil fuels accounts for 25 percent of the world's total emissions. So when you choose a clean energy plan for your home or use solar power, you’ll help cut carbon emissions.
Upgrading to renewable energy in our homes is an important step to phase out fossil fuels. The good news is that more people are making the switch, and solar power at home is on the rise around the world. Making this switch sends a clear signal to energy providers and politicians that we want a cleaner energy system.
Electricity from sources such as wind, solar, geothermal and hydro and nuclear produces zero emissions at the point of generation.
Emissions from electricity generation and heat production account for 25% of the world's total greenhouse gas emissions.
Globally, the levelized cost of energy for residential solar photovoltaics (PV) fell between 2010 and 2019, with markets showing a 42% to 79% cost decline.
More people are choosing solar. Residential solar matched commercial solar for the share of solar PV net capacity installations in 2020
Research shows that when you install solar panels, your friends and neighbors are more likely to do the same.
So, What Exactly Is Community Solar? Neighbors who are unable to build their own solar systems can join together, build a larger and more cost-efficient solar array nearby, and use the energy it provides to power their homes.
The typical solar fraction for residential solar heating systems is between 50% and 70% in the EU and US.
Impact metric calculations
To determine the carbon emission reduction estimates related to switching to a clean energy supplier or installing solar, the following calculations were performed:
(# of people in the household) x (monthly residential electricity consumption per capita) x (100% electricity effectively sourced from renewables) x (country-specific grid electricity carbon intensity) = kg CO2e reduction / month
