A responsible attitude to nature should be the goal of all countries of the world and not just the European Union. An increasing reliance on fossil fuels has been, polluting the environment which has further led to a global climate change, threatenings the very existence of the planet.
An efficient use of renewable energy resources (RES) may be a solution. These resources derived from ongoing natural processes, such as solar radiation, wind, water flow (hydropower) and photosynthesis which make plants build biomass and natural heat flow (geothermal energy), which do
not totally exploit the energy source itself.
We therefore, need economic incentives to widespread the use of renewable energy resources around the world extenisvely.
Photovoltaic energy is one of the fastest growing forms of energy use. This is the energy that comes from the sun in the form of solar radiation. Using photovoltaics, solar energy can be used for various purposes in an urban environment, household, industry, etc. Photovoltaic power plants are widespread in Europe (Germany, Spain, Switzerland, etc.). Their operation is quiet, they are visually unobtrusive. There is no need for extra fuel, which makes them environmentally friendly. The thesis discusses active noise protection (noise barriers) and photovoltaic (PV) power plants. Combining noise barriers and PV power plants simultaneously protects the environment from excessive road noise and convers solar energy into a direct current electricity. Existing noise barriers can form basis for installing PV power plants and increase their intended use.
