The United States is the largest and the most influential economy has some responsibility towards the world where it should use its influence to help save the world from an extinction-level threat that has surfaced in the form of Climate Change.
The United States says it has been making changes to its high carbon footprint economy to reduce its carbon footprint, but the actions don’t match the words quite yet. Fossil fuels such as petroleum, natural gas, and coal continue to dominate energy U.S. consumption. Renewable energy is showing growth, but it is too slow to meet any climate goals in the United States and globally. Meanwhile, climate scientists warn that we are running out of time to reduce greenhouse gas emissions. The world has just 11 years to cut emissions by 45 percent and must achieve carbon neutrality by 2050 to prevent temperatures from rising more than 1.5 degrees C. This necessitates immediate action and an economy-wide decarbonization program on an unprecedented scale. The renewable share of energy consumption in the United States was 11.4 percent in 2018, reaching a record high of 11.5 quadrillion Btu. Compared to that, renewables’ share stood at 6 percent in 2005. Solar and wind showed the largest growth, driven largely by capacity additions.
The potential for renewable energy in other sectors remains largely untapped. the use of renewable electricity in transportation and for heat in homes and industry should be encouraged, as they make up a significant portion of U.S. energy consumption and this could go a long way to reducing emissions and meeting long-term climate goals.
