Understanding the Current Energy Scenario and Its Future Implications
The global energy landscape is undergoing rapid changes that affect economies, environments, and societies worldwide. Rising demand, shifting sources, and evolving technologies create a complex picture that requires careful analysis. This post explores the current energy scenario, highlighting key trends, challenges, and what the future might hold.
The Current Energy Mix
Renewable Energy, Green Energy, Ecofriendly products, environment and nature and such words have now become "fads". Such words have started to get a place of honor in reading everyday writings, in fact, if we use such words in our conversations, people look at us with respect. Still, it is a good thing that people have now started talking about the topic of environment and nature. In this book, we are going to learn about one of the many latest energy sources, Solar Energy.
Renewable energy is energy that does not decay or decrease after use, but is able to provide new energy again. Solar, Wind, Hydroelectric, Biogas and Biomass are all renewable energy sources. In this book, we will only learn about solar energy. In daily use, we use the words Power and Energy in the same sense; but physics differentiates between the two. Physics says that energy is the ability to store energy. Anyway, in this book, we will use the word energy in the sense of electrical energy. Also, since this information is technical in nature and many English words are more familiar to us, we will use both types of Marathi and English or their convenience.
Today, the energy situation in our country is not as good as it should be. We are a developing nation and our economy has also become dynamic. For sustainable development and economic progress, it has become necessary to have uninterrupted electricity supply to factories, commercial establishments and households of all levels of society. This is called energy security and it has become as important as food security. The issue of energy security can be solved through government policies and far-sighted strategic decisions. Sustainable development and economic progress unfortunately have a direct impact on the environment. It is also related to climate change. The negative impact of progress and industrial development on the environment can be offset to a large extent by using solar energy.
The statistics of our country regarding energy consumption are worth studying. Today, we still mainly use fossil fuels for energy. We meet our needs using coal - 40%, oil - 22%, gas - 8% and the remaining 30% from other sources. Out of this other 30% of energy, we use only 1% of solar energy. The potential to generate solar energy in our country is huge! In comparison, despite our geographical location being favorable for solar energy, we generate very little solar energy. India is the sixth largest energy or electricity consumer in the world. If we consider the world, 80% of the population lives in underdeveloped and developing countries and these 80% of people use only 30% of the electricity generated in the world. There is a huge gap between electricity production and electricity consumption in our country. Our total electricity production is 360 GW, out of which only 300 GW is available for consumption. This difference is due to maintenance, line faults, power theft, and the time difference between power generation and demand. The demand for electricity is increasing day by day, and solar energy is a better alternative to fossil fuel-based electricity.
Where electricity is available in abundance, the area develops. And where there is development, the demand for electricity increases. The government divides the area into urban, semi-urban and rural according to population. The availability of electricity in rural areas is very low and due to this, the pace of development is also very slow. Rural areas are deprived of amenities due to this. Abundant availability of electricity can lead to sustainable development of rural areas and can improve the standard of living of the people. In India, the government started the rural electrification program in 1950. Due to remote areas and far-flung houses, electricity could not reach every household till date. The task of supplying electricity to households through the national grid was becoming expensive and these government schemes did not have much impact until 2016. Solar energy can be an effective solution to this problem. It is easier and less expensive to generate electricity for that village or village in villages and supply electricity to households. Installing solar panels on the roof of each house and generating electricity for that house is also a good option. In rural areas, every house, establishment or factory can become self-sufficient in terms of electricity by using solar energy.
Solar energy is not cheap for domestic use, hospitals, schools, agriculture, communication, etc., but it can definitely be a viable and healthy option. If training is provided in the rural areas of the country on how to generate energy as well as how to use it, the need for energy can be reduced. For example, many people install pumps in cities and villages without knowing how much capacity of a pump can meet their water needs. For example, if my daily water needs are met by a 2 HP pump, many people install a 5 HP pump thinking, "If I'm going to install one, I'll install a bigger pump." This situation is very obvious. In this situation, we increase our electricity bill unnecessarily. If such training is provided in rural areas, identifying our electricity needs and generating enough electricity, the need for electricity can also be reduced and if solar energy is generated for our consumption, the rural areas will become self-sufficient and their development can be achieved quickly and sustainably.
The purpose of this book is not just to collect information, but by using this information, non-technical people, whether they are in urban, semi-urban or even rural areas, can become self-sufficient in terms of energy by generating solar energy. This is an attempt to present this information in simple and useful words for people without a technical background. The knowledge of generating solar energy can also become a means of business or self-employment for many people. There are also some villages in the country where access to traditional energy, i.e. electricity, will be difficult even for the next few years. The information in this book has been compiled with the aim of being able to meet our electricity needs by putting it into practical use, so many demonstrations and pictures have been used abundantly. Solar energy revolution is bound to happen, let us participate in it on time and become self-sufficient in energy.
