Solar energy damages the environment badly

Environmental protection and solar energy

The most important issues of our time are probably climate change and environmental protection. The use of solar energy makes a contribution to climate protection. Solar is one of the clean energies. More solar thermal systems and photovoltaic systems are being installed from year to year. The solar energy is available unlimitedly. That is not the case with gas or coal. The resource of solar energy is inexhaustible and good for the environment.

Brief definition of terms

When one speaks of solar thermal systems, one speaks of heat. Solar thermal systems are used for heating support and hot water preparation.

Photovoltaic systems are used to generate electricity. For this purpose, electricity is actively generated using solar energy. These two types of solar energy differ in their different technologies.

Emission reduction through solar energy

According to data from the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, five million tons of CO2 could be saved through the use of solar energy in 2009 alone. These savings increased from year to year.

Electric heating produces 603 grams of carbon dioxide per kilowatt hour. This gas is harmful to the environment. It is held responsible, for example, for global warming and the melting of the polar ice caps.

In contrast, a petroleum heater produces 295 grams of energy per kilowatt hour. When using solar energy, no fuels are burned. This technology therefore saves a lot of emissions. That protects our environment.

The use of solar street lighting not only saves energy, but the installation is also environmentally friendly. Because there is no need to dig to lay power lines. Solar street lights do not need to be connected to the power grid.

The sun as the energy source of the future

Our sun provides 10,000 times the world's energy consumption every day. Thanks to good subsidies and falling market prices, solar energy is also becoming more and more interesting for private households. Solar energy is converted into electrical energy by photovoltaics. In contrast, solar thermal systems use infrared rays to generate heat.

Solar energy is an inexhaustible source of energy

The use of solar energy will become more and more important in the future. Because it is available indefinitely. Energy from the sun does not cause any fine dust, such as soot particles or greenhouse gases. The most important argument, however, is: The sun doesn't bill us!

The use of photovoltaics in mobility

In Austria, the mobility sector accounts for 28% of greenhouse gas emissions. Electricity plays an important role in mobility. The trains, subways and trams as well as trolleybuses are already equipped with electric drives. However, private transport still predominates. That is why the expansion of the public transport network is a top priority.

Solar energy as an important factor for the transport infrastructure

Photovoltaics in mobility can look back on great pioneering projects in recent years. For example, the circumnavigation of the world by the solar ship “Türanor Planet-Solar”. Or just like that of the solar airplane "Solar Impulse2".

Photovoltaics also play a role in transport infrastructure. There are various areas of application that can easily be covered with electricity from photovoltaic systems.

For example:

  • Timetable lighting
  • Parking ticket machines
  • Traffic information systems
  • Emergency telephones
  • Navigation systems
  • Solar street lighting

In addition, traffic lights with solar power supply can be used on construction sites. Because they are flexible in construction because no connection to the power grid is necessary. Photovoltaics is already used in roofing systems. There are also own photovoltaic carports, which are interesting for private individuals as well as for companies.

Street lighting with photovoltaics

This technology is also used in solar street lights. The solar street lights are also equipped with a photovoltaic panel. You can generate the electricity you need yourself with the help of the sun. The electricity is then stored in the integrated memory and emitted in the form of light in the evening. Solar lanterns are also already being offered for private homes. This type of application is particularly interesting for supermarkets as well as for company parking lots. In addition, the lighting is quick and flexible to install and there are no running costs.

The environmental balance of solar energy

It's not just the environment that benefits from solar power. The use is also effective from an economic point of view. Photovoltaics therefore has a positive environmental balance. Not only are fossil fuels saved and carbon dioxide emissions reduced. No! More energy is generated over the service life than is necessary for production. As a result, solar power protects our environment and reduces greenhouse gas emissions. This reduces the damage to the environment. For example the greenhouse effect or the attack on the ozone layer.

Final positive facts about solar energy

Viewed over its entire service life, a photovoltaic system produces 6 to 14 times as much energy as was required for its production. Another plus point for the environment is that a solar system can be recycled up to 95%. The material obtained from recycling can be used for the production of a new plant.
