Usually the largest single cost factor is lighting. Obsolete light bulbs only use about ten percent of the electricity to make light. 90 percent are lost as heat. They produce heat rather than light, because they are based on a glowing filament made of tungsten. Modern LEDs use almost all of the electricity to make light. You can clearly notice this from the fact that they stay cool, i.e. there is much less loss. A good LED needs about a tenth of the electricity to produce the same amount of light. And because it does not heat up so much, it lasts much longer. And: The price of LEDs has come down so much, that exchanging them for regular light bulbs pays off within one or two years. The same is true for industrial lighting systems which often use mercury vapour lamps. These, too, use up a lot of electricity and can easily be replaced by LEDs.
Are residential solar panels worth it? Estimate residential solar panel cost. Solar panels aren’t cheap: with installation, an average residential 5kW size system runs between $3 and $5 per watt, or $15,000 to $25,000, before tax credits and incentives, according to the Center for Sustainable Energy.

Solar electricity yields are highest between spring and autumn. This is also the time of year when the garden requires the most work. You can very conveniently run electric lawn mowers, hedge trimmers or lighting off solar electricity. If you have a solar battery, you can use it to power LED lights in your garden in the evening and at night. A garden sauna can be heated up using surplus electricity during the day, so that it is ready for use in the evening
There is a reason why solar energy has become a trending topic when talking about renewables. While it has been widely criticised for being expensive or not very efficient, solar energy has now proved to be extremely beneficial – not only for the environment but also financially speaking. Additionally, due to the higher demand, the technology has been improved considerably, turning into a significantly efficient source of clean energy.
Advantage of Solar Energy : Solar energy can be used for diverse purposes. You can generate electricity (photovoltaics) or heat (solar thermal). Solar energy can be used to produce electricity in areas without access to the energy grid, to distill water in regions with limited clean water supplies and to power satellites in space. Solar energy can also be integrated into the materials used for buildings. Not long ago Sharp introduced transparent solar energy windows.
Disadvantage of Solar Energy : The more electricity you want to produce, the more solar panels you will need, as you want to collect as much sunlight as possible. Solar panels require a lot of space and some roofs are not big enough to fit the number of solar panels that you would like to have. An alternative is to install some of the panels in your yard but they need to have access to sunlight. If you don’t have the space for all the panels that you wanted, you can opt for installing fewer to still satisfy some of your energy needs.
