Renewable energy is fuel generated by source and that source is renewable means that can be restored or readily replenished by nature. These sources include solar energy, wind energy, and biomass energy. As demand for fuel is increase throughout the world alternative and renewable energy sources are emerging as economical and dependable option to traditional oil/coal based fossil fuels. To reduce carbon footprints on the environment several options are available. There are several benefits for government for the favor of implementation of green energy solutions. The government should adopt policies to support market-based energy pricing, energy efficiency in the commercial and residential sectors, improved governance within the energy sector, and scaled up deployment of renewable energy.

Government can take advantage of solar rays by converting them into usable energy. Solar photovoltaic on rooftops or above parking lots is the easiest way to incorporate renewable energy into energy portfolio. Wind energy projects capture the kinetic energy of wind, converting it into energy that can serve as a direct use, onsite source of energy. Wood biomass can be converted into energy through a gasification process that heats wood in an oxygen deprived environment, transforming the wood into gas, and gas into energy .

Government can get benefits in several ways by implementing green energy solution one such benefit is reduction in import of fossil fuel from other countries and self-dependency for energy generation to meet nations energy need. Secondly, potential to reduce electricity costs. Several other factors that could be considered are

As traffic signals are in continuous use, they consume a significant amount of energy. In addition, the incandescent bulbs used in most traffic lighting and signals typically have a one-year lifespan and need annual maintenance. The signals, while vital for resident order and safety, are not economical. LED bulbs typically use 80 to 90 percent less energy than incandescent bulbs and have a five-to-seven-year warranty before replacement or maintenance is required. Increased road safety for residents, LED bulbs emits light more evenly, with brighter luminosity. Reduced operating expenses, less frequent replacement of bulbs requires less staff time. Convenience for residents, free traffic flow reducing drive time [3].

Wastewater treatment plants

In addition to energy savings, treatment plant improvements can extend equipment life and improve operational control. Optimize biosolids systems decrease the use of chemicals. Improve efficiencies and reduce the need of fossil fuel sources.

Landfill gas to energy

Landfills are an existing source of a clean-burning, renewable commodity. This gas can be used to reduce overall greenhouse gas emissions, capturing up to 90 percent. Generate energy to power your community or industry that provide an additional income stream for the community and meet compliance requirements and mandates. it also improve local air quality.

Stable energy prices

Renewable energy is providing affordable electricity across the country right now, and can help stabilize energy prices in the future. The costs of renewable energy technologies have declined steadily, and are projected to drop even more. For example, the average price of a solar panel has dropped almost 60 percent since 2011. The cost of renewable energy will decline even further as markets mature and companies increasingly take advantage of economies of scale. While renewable facilities require upfront investments to build, once built they operate at very low cost and, for most technologies, the fuel is free. As a result, renewable energy prices are relatively stable over time. In contrast, fossil fuel prices can vary dramatically and are prone to substantial price swings. Using more renewable energy can lower the prices of and demand for natural gas and coal by increasing competition and diversifying our energy supplies. An increased reliance on renewable energy can help protect consumers when fossil fuel prices spike [5].

Reliable and resilient energy system

Wind and solar is less prone to large-scale failure because they are distributed and modular. Distributed systems are spread out over a large geographical area, so a severe weather event in one location will not cut off power to an entire region. Modular systems are composed of numerous individual wind turbines or solar arrays. Even if some of the equipment in the system is damaged, the rest can typically continue to operate. The risk of disruptive events will also increase in the future as droughts, heat waves, more intense storms, and increasingly severe wildfires become more frequent due to global warming. Renewable energy sources are more resilient than coal, natural gas, and nuclear power plants in the face of these sorts of extreme weather events. For example, coal, natural gas, and nuclear power depend on large amounts of water for cooling, and limited water availability during a severe drought or heat wave puts electricity generation at risk. Wind and solar photovoltaic systems do not require water to generate electricity, and they can help mitigate risks associated with water scarcity [6].
