How can i contribute to fight against global warming by opting for rooftop solar system? Demonstrate.

• Reducing Carbon Emissions: The average household in the United States consumes approximately 10,972 kilowatt-hours (kWh) of electricity per year, according to the U.S. Energy Information Administration (EIA). By installing a rooftop solar system, which can typically generate around 1,200 kWh to 1,500 kWh per year per kilowatt of installed capacity, you can offset a significant portion of your household's electricity consumption with clean, renewable energy. For example, a 5-kilowatt (kW) rooftop solar system could offset around 6,000 to 7,500 kWh of electricity consumption annually, reducing carbon emissions associated with fossil fuel-based electricity generation.

• Promoting Renewable Energy Adoption: As of 2021, solar energy accounted for approximately 2.3% of total electricity generation in the United States, according to the EIA. By choosing to install a rooftop solar system, you contribute to the growth of solar energy adoption and help diversify the nation's energy mix with clean, sustainable alternatives. With more households and businesses embracing solar power, the share of renewable energy in the electricity sector continues to increase, driving investments in solar infrastructure, technology innovation, and job creation in the renewable energy industry.

• Mitigating Climate Change Impacts: The Intergovernmental Panel on Climate Change (IPCC) estimates that global greenhouse gas emissions must be reduced by 45% from 2010 levels by 2030 and reach net-zero emissions by 2050 to limit global warming to 1.5 degrees Celsius above pre-industrial levels. By reducing your household's carbon footprint through rooftop solar and other energy-saving measures, you contribute to global efforts to mitigate climate change and safeguard the planet's ecosystems, biodiversity, and human health from the adverse impacts of rising temperatures and extreme weather events.

• Building Energy Independence: In the United States, residential electricity prices average around 13.31 cents per kWh, according to the EIA. By generating your own electricity from rooftop solar panels, which typically have a lifespan of 25 years or more, you can hedge against future electricity price volatility and reduce dependence on centralized power grids and fossil fuel-based electricity providers. Rooftop solar systems enhance energy security, resilience, and self-sufficiency, empowering households to withstand grid outages, natural disasters, and disruptions in energy supply chains.

• Financial Savings and Long-Term Benefits: The cost of installing a residential rooftop solar system varies depending on factors such as system size, location, incentives, and installation costs. According to the National Renewable Energy Laboratory (NREL), the average cost of a residential solar system in the United States ranges from $2.81 to $3.57 per watt before incentives. With incentives such as the federal solar investment tax credit (ITC) and state-level rebates and incentives, homeowners can significantly reduce the upfront cost of solar installation and achieve financial savings over the system's lifetime through lower electricity bills and potential revenue from excess solar energy exports to the grid.

By considering these numbers, homeowners can make informed decisions about the environmental, economic, and social benefits of investing in rooftop solar and contribute to the transition to a more sustainable energy future.
