Energy policies aim to promote renewable and eco-friendly energy sources while mitigating their associated environmental effects, such as protecting biological communities from fossil fuel mining or drilling operations or controlling air pollution from combustion of fossil fuels.
Government funding of research and development for advanced technologies like carbon capture and storage, lower cost batteries and electric vehicles is also included in such plans.
The U.S. Energy System
Energy security is of great significance for national economies, the welfare of populations, and military operations. Diversifying sources, routes, technologies, supply chains and technologies is essential in providing reliable energy supplies.
America’s energy system is comprised of power plants, transmission and distribution lines, end users and various end-use sectors. Power plants generate electricity using various types of fuel sources – fossil fuels like petroleum and natural gas as well as nuclear energy or renewable sources like wind or solar power are commonly employed.
NCEA’s Leading Energy Indicators (ESIs) offer an annual snapshot of how the U.S. energy system is evolving, while their weighted indicator groups reflect their changing importance to national energy security. As oil’s share has diminished over time, its vulnerability to oil vulnerability has decreased while alternative energy technology’s access to minerals required for its support has grown considerably more significant in affecting this indicator group.
Electrification
An increasing number of sectors–ranging from buildings and cold chains, transport, and industry–are making the transition away from fossil fuels towards solutions powered by electricity. Electrification can significantly lower carbon emissions in these sectors while simultaneously helping utilities lower costs by shifting demand during times with lower electricity rates, improving efficiencies and resilience, or simply cutting carbon emissions altogether.
Smart grids that enable electric vehicles to switch their use between daytime and night-time usage can reduce straining networks during periods of peak demand, and give utilities operational flexibility to discharge or shape electricity at optimal times (e.g. when excess renewable energy becomes available) at lower costs than building massive new infrastructure to store or dispatch energy during peak hours. Furthermore, electrification accelerates energy transition by decreasing fossil fuel usage – this helps ensure affordable, clean and reliable supplies of energy are always available – an integral element of energy security.
Renewable Energy
Renewable energy comprises any source that replenishes itself more rapidly than it’s consumed, such as wind, solar, biomass and hydropower. Renewable energy may also include recycled waste and biofuels like ethanol or biodiesel which are produced using plant oils, animal fats or microalgae oil sourced from renewable resources.
Choose renewables over fossil fuels to lower greenhouse gas emissions that contribute to climate change and global warming, with most renewable sources producing no or minimal air pollutants whereas burning fossil fuels produces carbon dioxide and other emissions when producing electricity or transportation needs.
Businesses can play a pivotal role in driving renewables by installing on-site solar and wind infrastructure or purchasing renewable power through green electricity certificates or power purchase agreements (PPAs). The cost of renewable technologies continues to drop as economies of scale, learning, and other factors advance technological innovation; additionally they create three times more jobs than fossil fuels.
Energy Security
Modern living requires vast quantities of energy for homes, transportation and industry as well as basic services like lighting and heat. Unfortunately, however, not everyone worldwide has access to reliable yet cost-effective energy supplies and must rely on less concentrated forms of fuel that pollute more heavily, often located in unstable regions.
Energy security aims to ensure access to energy while mitigating its negative environmental and economic effects. Policy approaches involve encouraging renewable energy use, energy efficiency measures and diversifying supply sources while decreasing fossil fuel dependence as well as supporting new technologies and infrastructure development.
Countries develop and implement energy policies tailored to their own particular interests. International agreements may bring countries together towards common goals, such as the Paris Agreement on climate change or improving electricity grid resilience and security against cyberattacks and extreme weather events. Local municipalities may also develop their own energy policies such as building energy codes or energy efficiency standards.
