The energy which we obtain from the sun is called solar energy or radiant energy. The sun's energy is stored in coal, natural gas, water and wind. Coal, oil, and natural gas are known as fossil fuels. Fossil fuels were formed over millions of years ago when the remains and fossils of prehistoric plants and animals sank to the bottom of swamps and oceans. These animal and plant remain were slowly covered and crushed by layers of rock, mud, sand, and water. The pressure of all those layers caused the plants and animals to break down and change into coal, oil and natural gas. We use the energy in these fossil fuels to make electricity. As of the year 2019, most of the energy we use comes from fossil fuels. However, fossil fuels are known as non-renewable sources of energy. They cannot be used over and over again. This means that one day they will run out! The energy source that uses collectors to heat water or air in buildings is

Noise is a common problem in both urban and rural areas, traffic noise in particular. Trees and shrubs are not only visually attractive but also can make effective noise barriers. Therefore when space permits we have to plant more trees and shrubs in areas where there is noise problem. By doing this noise can be reduced by six decibels over a distance of 30 metres. The only thing we have to keep in mind is that the planting should be particularly dense, the trees which have dense foliage and relatively vertical orientation of arrangements should be planted. It will completely screen the source of noise. If there is any gap in barrier it will still allow noise to penetrate. Single layer of trees is worthless as a noise barrier. Due to inter-reflection, multi-rows of trees are more effective. The planted trees must be taller. We can reduce noise level by 1.5 decibels with each additional 3 feet of tree height When the opportunity to use trees is restricted a combination of shrubs and tall grass can be used. Instead of tarmac or gravel surfaces soft grass ground cover is preferable. It will absorb noise rather than reflect it. Rows of trees, shrubs, crotons, ground covering plants, climbers and their flowers not only reduce noise and provide a beautiful backyard they also help block wind, provide shade, and absorb traffic pollution.
