Today the situation is harmful to many people, cause an irreversible damage to the environment. The reason for this is using natural resources greatly unreasonable. The aim of ecology is one of the highest priorities to protect natural resources and can multiply.
Ecology and energy saving – these two concepts inextricably linked. The electricity we use every day for the organization is his way of life. Thermal power plants, the most polluting day operations of this energy supply to us on Wednesday. Frankly, if we are to save our planet, alive and well, energy that we need to do sparingly and appropriately. Therefore, we can reduce the harm that is applied to the plant in nature.
Energy and environment
The level of development the society a designated amount of energy spent on a man. Today, the primary energy sources oil, coal, natural gas. Work, Heat and energy boiler and TPP effects on the environment in a different way:
- the atmosphere came to our planet, many hazardous waste
- harmful substances to shed water and hot water,
- a large amount of consumed oxygen,
- large plots and polygons used under the soil for waste burial.
Soil pollution, air and water why is it called the greenhouse effect. Resulting air rises on the planet, and thus can have irreversible consequences for other running. It should be remembered in the same way, energy sources such as oil, gas and coal, hard-packed, dry them for their rational use can in so short a time.
Alternative energy sources
Modern teaching search to find alternative energy sources.
Under the concept "energy source" or the term allow natural substances to get the energy for events.
Counter of alternative energy sources-traditional sources. Traditionally, as stated above, among them Oil, Gas and coal. Required for alternative sources to reduce the negative effects of conventional energy sources and environmental damage. Current alternative energy sources are able to provide:
- solar energy
- wind energy
- water energy
- energy land
- biofuels
To obtain solar energy solar radiation. Solar energy is considered a renewable energy source. The term "renewable resource" ima inexhaustible energy sources. Plus, this kind of energy, eco-friendly, so the import process requires energy, emissions, hazardous waste and pollute the environment. Solar power plants with solar energy. Such energy has its advantages and disadvantages. Among the advantages, accessibility and, as noted above, a full security environment.
Current weather conditions for the cons, dependency, and on the time of day, why you can use that kind of energy on a regular basis, only in certain climatic regions. Applies energy power plants that are used in their production high cost and shortcomings, such expensive items. Also exploitation of solar energy stations that require the use of large areas.
Wind energy conversion the kinetic energy produced by wind in the atmosphere, any other energy form. Different devices used for this are, for example, wind turbines, windmill sails. All types of renewable energy including wind energy. In addition, wind energy can be used and is safe for the environment. Pros use the same energy and something of the Windy windy slopes may be connected to one, easy-to-use, maintenance-free, long load, and at a great cost.
But it's definitely there and some cons, for example, do not install the power such an energy, depends on the person and nature, and the power of the wind. Some opponents of junk cons this technology to classify birds, danger, distortion intake of TV and radio signals, the landscape changes.
Extract water, energy to convert to kinetic energy in a body of water for the purpose of an electrical energy. Energy is achieved by using hydropower. Power a turbine that produce electricity have an impact on water flow. The use of these plants is an obvious plus, what is this inexhaustible source of energy. In addition, hydropower for a safe environment. The energy obtained in this way are cheap enough. Along with the advantages there are disadvantages, for example, dependency, weather, climate and natural conditions. From the station, built only in certain places. Another drawback is, the energy obtained in this way to keep this difficult to apply at a later date.
Within the scientific community called the inner world geothermal energy heat energy obtained through the use of electricity. Thanks to his use of mined geothermal power plants. Secretes large amounts of energy for cooling a planet, a thousand times more than a fossil fuel highlights. The world energy is a renewable energy source. The advantages of this method mining electricity can be connected, and the environmental conditions. The cons are as follows high cost of construction and services, such as power plants. The station is also considered the workstation may contain harmful substances which cannot completely steam flow occurs in a secure environment.
Under the concept animal or vegetable fuel biofuel is understood that you receive. Maybe three kinds of biofuel:
- solid
- liquid
- gas
Solid biofuels, this wood sawdust, straw. Today, people grow special energy, forest, rocks composed of fast growing tree.
Mostly bioethanol and biodiesel liquid fuel is presented. Mainly sugar cane and corn to produce bioethanol. The obtained biodiesel is oil, vegetable and animal.
Represent biofuels biogas gas processing, bio-hydrogen, and methane. Biogas produced foods fermented organic waste. Bio-hydrogen – the hydrogen from imported biomass thermo chemical or a biochemical way.
Results
Today scientists, receive to reduce the consumption of resources on the energy consumption of Unbreakable humanity. Every day requires energy, and more and more the source remains less. It is important at this stage learns to save and consume energy rationally, obtained from conventional sources. An even more significant development, a new, inexhaustible, sustainable energy sources, this helps to keep our environment alive and healthy in the next year.
