Solar energy is a resource that is not only sustainable for energy consumption, it is indefinitely renewable (at least until the sun runs out in billions of years). Solar power can be used to generate electricity, it is also used in relatively simple technology to heat water (solar water heaters). The use of skylights in home construction can also greatly reduce energy expenditure required to light rooms in a homes interior during the day.
Solar panels also require little maintenance. After installation and optimization they are very reliable due to the fact that they actively create electricity in just a few millimeters and do not require any type of mechanical parts that can fail. Solar panels are also a silent producer of energy, a necessity if dealing with picky neighbors. Indian government has also introduced generous tax credits for individuals and companies that invest in solar and other clean energy systems.
No matter what kind of energy source you use—coal, natural gas, nuclear power—there are always three steps to powering your home: generation, transmission, and distribution. Each of these means additional costs that get passed on to you.
