Do We Need Renewable and Solar Energy

In a time when the major nations of the world are looking to find more sustainable energy sources, renewable energy must play a key part of any long term strategy. Renewable energy comes from natural sources such as the sun, wind power, wave energy, geothermal, biomass and hydroelectric power.

Sustainable energy sources are attracting increased attention due to the scarcity of fossil fuels. The value and cost of non-renewable energy sources is rising due to the high demand to support our current way of living, with the reduced supply of these sources.

The focus is shifting toward sustainable energy sources, due to the world depletion of fossil fuels. The gap between the availability and demand of such energy is significantly increasing, therefore value and cost of these energy sources is rising. The most widely used renewable power source is solar power, Latin for ‘sun’, a powerful source of energy. There are two forms to contain the energy – thermal and photovoltaic. Thermal power converts sunlight into heat, applying it to a steam generator in order to warm buildings, heat water and generate electricity. Photovoltaic power uses solar cells or panels, when sunlight strikes the semiconductor material and creates an electric current. Other solar technologies concentrated power plants, solar towers and portable solar.

The energy from the sun can be captured across the world, however, areas on or near the equator have a greater solar intensity. Solar energy has many advantages, for example, the renewable aspect, non-polluting and relatively maintenance free. Solar energy has a few disadvantages, geographically, locations near the poles of the earth are restricted in gaining energy from the sun, cloud cover can reduce efficiency and PV panels are relatively expensive.

Industrial and domestic users value Sustainable energy sources highly. Corporations and industry use these new technologies to vary their energy sources, improve efficiency and reduce overhead costs. Renewable power can support different scale applications, including the use of renewable energy to produce electricity, heat, steam, lighting, cooling, water heating, and mechanical energy.

Property developers and utilities providers are turning to use alternative energy sources to produce sustainable power for villages, small towns and cities. It is clear that over the last few decades, increasing energy demands, environmental problems and declining fossil fuels have made us look at alternative, more sustainable energy options.

Different climates across the globe mean certain types of renewable power technologies are more effective in certain areas. It is seen that the United States use more solar power plants, Europe uses power from wind, and China has the most hydroelectric power plants.

Using renewable energy is key to sustainably fueling our homes in the future. For expert advice on Renewable Energy Scotland and Solar panels Glasgow contact Absolute Solar and Wind.
