Energy is a powerful commodity that controls the functioning of the entire world. Solar energy obtained from the light rays of our Sun has seen a recent rise in its popularity, especially as a source of energy in many households across the globe.
There is a possible explanation to this situation. Energy production from non-renewable sources like coal and petrol will be difficult / will be less viable in the near future not only because of the reduction in their reserve but also due to the high costs quoted by the countries which hold their reserves. Therefore the entire globe has become busy in developing renewable sources of energy. Since sunlight is available in abundance, solar energy has become a better alternative to other forms of energy.
Solar energy has its pros and cons, but the pros outweigh its cons. An advantage of solar energy is that it can be harnessed without having to build expensive power plants. Families can install solar panels on their roofs and generate adequate amount of energy to run household appliances such as lights, fans, heaters, refrigerators and so on. It is very simple and just needs the Sun out there in the sky. It is also clean and does not pollute the land or the air.
On the other hand, solar energy grids come with their own price which is unaffordable to the underdeveloped and developing countries around the Equator. These are the countries which benefit most from the solar energy owing to their geographical location. In the developed western world the situation is quite the opposite. These countries are cold and receive only a small amount of sunlight. Consequently, not much solar energy can be generated there. Despite these short comings, Germany has emerged as the world leader in solar energy production according to a recent report issued by WHO. Germans have well understood the proverb “Make hay while the Sun shines”. It is now time for the entire world to follow suit.
To conclude, solar energy is gaining popularity because it is safe and clean. In the coming years as the technology develops and solar panels become more affordable, its popularity will only increase.

It is true that solar energy has become an efficient source of energy in many nations around the world. Although it has a few downsides, I believe that the merits outweigh them. This essay will discuss the primary reasons for the popularity of solar energy and explain its pros and cons with relevant examples.
The main reason for the popularity of solar energy is that is that it is an abundant source and it is eco-friendly. If you live in an area where sunlight is plenty, you can easily harness solar energy to power your homes. Needless to say, more and more households now use solar energy for heating water or cooking food. Governments are also encouraging solar power because of its environmental benefits. Another reason is that as the population grows, the need for energy also increases and conventional sources are not able to fully satisfy this.
Eco-friendliness is certainly the biggest advantage that solar has over conventional sources of energy. Conventional sources like fossil fuels are fast depleting. According to some estimates, we may run out of fossil fuels in the next 20 or 30 years. Solar, by contrast, is an abundant source of energy. There is no danger of it getting depleted. Another advantage of solar power is that it does not pollute the environment.
On the down side, solar energy can only be harnessed in areas that receive a lot of sunlight. During winter or rainy season, when the sun is not fully visible, not much energy can be generated. Another downside is that the technology is still in its nascent stage and solar power continues to be more expensive.
To conclude, solar energy is becoming popular because it is eco-friendly and renewable. Its main advantage is that it is an excellent source of energy in places where sunlight is abundant. The main disadvantage is the high installation cost.
