1) Serious depletion of natural resources such as oil, coal and natural gases etc...
Increasing prices of oil, thus electricity usage at home will become more expensive.
2) Environmental problems, huge amount of carbon dioxide emission from the burning of petroleum to produce electricity, toxic gases from cars.
Solar Panel Basics: (To Add on to what I've learnt in Sabbatical)
A solar panel (photovoltaic module or photovoltaic panel) is a packaged interconnected assembly of solar cells, also known as photovoltaic cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.
Because a single solar panel can only produce a limited amount of power, many installations contain several panels. This is known as a photovoltaic array. A photovoltaic installation typically includes an array of solar panels, an inverter, batteries and interconnection wiring.
There are mono crystalline solar panels or poly crystalline ones and amorphous. composed of a number of different crystals, fused together to make a single cell (hence the term 'multi'). Monocrystalline, as the name suggests, is constructed using one single crystal, cut from ingots. This gives the solar panel a uniform appearance across the entire module. These large single crystals are exceedingly rare, and the process of 'recrystallising' the cell is more expensive to produce. Amorphous offer better performance in higher temperatures, and have some benefits in shady locations.

How does a solar panel generate electricity?
You've probably seen calculators with solar cells -- devices that never need batteries and in some cases, don't even have an off button. As long as there's enough light, they seem to work forever. You may also have seen larger solar panels, perhaps on emergency road signs, call boxes, buoys and even in parking lots to power the lights.
Although these larger panels aren't as common as solar-powered calculators, they're out there and not that hard to spot if you know where to look. In fact, photovoltaics -- which were once used almost exclusively in space, powering satellites' electrical systems as far back as 1958 -- are being used more and more in less exotic ways. The technology continues to pop up in new devices all the time, from sunglasses to electric vehicle charging stations. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely and this is electricity!

These amazing little things help U to save electricity with the help of the most prehistoric but mandatory source of energy-the light! However, most solar projects normally take roughly 11 to perhaps 20 years for installers to earn back money or to get returns.
