It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length. We are familiar with different types of energy. Using energy we are doing a huge work in our daily life. That"s why every body is trying to find to get energy cheaply. They are looking for a cheap energy source.

The energy we are using is very costly that"s why the world is looking for cheap energy. Now a days solar energy is a very cheap energy that is used in the house hold affairs. In Bangladesh solar energy is used in the rural area. The rural people are using solar panel. It is cheap than other energy. If many people use solar energy then the pressure of electricity will be low. And electrical energy will save. That"s why the cost of electrical energy will be low.

But there is a common problem for general people. How they can get the information about cheap energy. In the internet many websites are sharing a huge information about cheap energy. If we visit the websites we can get many information about energy in our country and the outside the country. We should know about meter reading and all information related to energy. If all the people know about it then they will seriously benefited. So using internet general people can get information about the source of cheap energy or how can they get the source of cheap energy.

The cost of energy depends on many criteria like the location of the source, the cost of fuel, the cost of maintenance, the cost of labor etc. If all criteria are filled cheaply then the cost of energy will cheap. If it is possible to collect energy without the help of others country then the cost will be low. And if the people become conscious about the uses of energy then the energy will be available and the general people will get energy easily. If energy will available then the cost of energy will low and people will get energy cheaply.
Gas is a source of energy and we are using gas for different types of work like cooking, gas turbine power plant, riding bus etc. Otherwise wind turbine is an another source of producing cheap energy. If we use energy like solar or wind then the cost of energy will low. Many companies are selling energy and giving discount for their regular or new customers. But if we save energy we will be also benefited in economically also.
