Renewable Portfolio Standards (RPS) are policies put in place by governments to encourage the increased use of renewable energy resources. The objective of RPS is to reduce reliance on non-renewable resources such as coal, gas, and oil, and shift to sustainable sources such as solar, wind, hydro, and geothermal.

Among the varied sources of renewable energy resources, solar and wind power are the most prominent ones. While solar has been rapidly gaining popularity in recent years, the wind power industry is still the fastest growing renewable energy resource. These two sources of power are just the tip of the iceberg when it comes to the range of RPS resources available.

Biomass is another significant source of RPS resource. Biomass comprises organic matter derived from living or recently living organisms, such as crops, plants, food waste, and animal manure. These substances are highly valuable as they can be converted into energy through several processes including combustion, gasification, and anaerobic digestion.

Geothermal energy is yet another RPS resource, which derives power from the earth’s heat. Geothermal energy is a highly promising technology that offers attractive benefits such as uninterrupted supply, significant cost savings, and zero emissions. In fact, it is highly recommended in areas that have volcanic activity or hot springs.

Hydroelectric power is another major sustainable resource, which is generated by harnessing the power of water. Hydroelectricity can be produced from large and small-scale systems, each suitable for specific regions and water bodies.

Multiple benefits come with the use of renewable energy sources under RPS policies. For instance, the increased use of these resources leads to job creation, minimal environmental pollution, improved air quality, and reduced greenhouse emissions. Furthermore, shifting from non-renewable sources to sustainable sources reduces the dependence on foreign energy, which is a significant step towards energy independence.

One of the significant barriers to the implementation of RPS policies is the high cost of adoption, coupled with the infrastructure needed to accommodate the new forms of energy. However, this is slowly becoming less of an issue as sustainable energy solutions become more affordable, and the demand for these methods increases.

In conclusion, RPS policies are an essential tool for transitioning to sustainable solutions in the energy sector. The diversification of the range of resources available provides consumers and governments with options that are tailored to fit their specific needs, promoting a sustainable future in the long term.
