Renewable Energy v/s Nonrenewable Energy (conventional energy) – Advantages & Disadvantages

While talking about renewable and non-renewable energy, it is quite confusing as to which one is worthy. Thus let us have a detailed comparison of renewable and non-renewable energy.

As we all know that there are different forms of energy available on earth. On the basis of exhaustibility, energy is classified into renewable energy and nonrenewable energy (also called as conventional energy). Renewable energy is a type of energy that is replenished naturally over the course of time. It is also known as green energy. This energy is generated naturally from sunlight, wind, tides, heat and rain. This type of energy cannot be exhausted and are comparatively cheaper forms of energy. No green house gases are emitted. Some of the types of renewable energy are solar energy, wind energy, tidal energy, biomass and geothermal energy. Nonrenewable energy on the other hand, is a type of energy which cannot be replenished or takes a long time to replenish. Fossil fuels, natural gas, coal, petroleum and uranium come under the category of nonrenewable energy. It comes out of the ground as solid, liquid or gaseous form. Once these resources are used, it is used for good.

Renewable Vs Nonrenewable energy


  1. Solar energy from the sun
  2. Wind energy from wind
  3. Tidal energy from the ocean waves
  4. Geothermal energy is the energy of the earth.
  5. Biomass energy is from agriculture and food waste.


  1. Petroleum also known as liquid fossil fuel formed within the underground sedimentary rocks.
  2. Coal is deposit of yesteryears plants which are found deep within the ground which when burnt produces huge amount of heat energy.
  3. Natural gas is found in deep rock beds along with coal and also the byproduct of petroleum.
  4. Crude oil is found deep underground within the sedimentary rocks.





The above mentioned are a broad comparison between renewable energy and nonrenewable energy. Both have its own merits and demerits. After a thorough study, I have come to a conclusion that renewable energy has an upper hand over nonrenewable energy considering the pollution aspect. Pollution hampers the ecosystem as a whole. All living thing like plants, animals, trees, shrubs, aquatic animals and mostly humans gets affected by pollution. The breathing capacity, reproductive ability, life span, capacity to withstand adverse climatic conditions and also immunity also gets affected due to pollution. Global warming affects the world as a whole. The climatic conditions change drastically, the seasonal variations change, the humidity increases and the temperature rises in this process. All these will finally affect the existence of mankind and all living creatures on earth. So to conclude, the green renewable source of energy should be used more and an alternative to nonrenewable source. More steps should be taken for its maximum utilization with minimal wastage. Steps should be initiated by the government to develop technology for the adequate use of these renewable resources. Though it is available in plenty and freely available, these energy sources are likely to be misused. Proper planning and measures should be taken to curb this practice. Recycled materials should be used more so as to minimize the use of available resources. On the other hand, the use of nonrenewable source of energy should be minimized so as to reduce pollution. Alternative energy source should be used to minimize the use of these nonrenewable resources. If all these above mentioned steps are adopted, the world will be a better place to live in.
