Who benefits from sustainability?

Note: For more information please click on the circles

Resource consumption of the industrial nations

The importance of a sustainable lifestyle and the use of resources is illustrated in the graph on the left, which shows the consumption of industrialized countries such as Germany or the USA. At this point in time, 3.1 earths would be necessary to cover the total consumption of Germany alone.
Wie viele Erden brauchen diese Industrienationen um ihren Verbrauch zu decken

Wackernagel (Global Footprint Network founder) about an ecologically functioning economy and sustainable lifestyle:
"Green technologies facilitate a sustainable lifestyle. They also bring benefits to our economy, such as new jobs and a better quality of life in cities. The only thing that we need more of is political will.".

What are the most important renewable energies and what advantages do they have?

Example of the benefits of solar in developing countries such as Bangladesh

Benefits for the environmental dimension of sustainability

  • Solar is an inexhaustible source of energy - we just have to use it: Solar energy as a natural source of electricity is not only sustainable but also renewable, meaning it is infinitely available. Theoretically, it would be possible - measured in terms of availability - to cover the entire world demand for electricity with solar energy alone, which is illustrated in the graph on the left.

  • No negative impact on the environment: During operation, solar parks do not produce any emissions and have no negative impact on the environment.
  • Solar replaces fossil fuels: Each solar system reduces the consumption of fossil fuels for energy production.
  • Solar energy slows down / stops global warming: Global warming threatens the survival of mankind, as well as the survival of numerous animal species. Fortunately, decades of research have led to efficient solar panels that produce electricity without supporting global warming. Solar energy is thus an essential component in the fight against global warming.

Benefits for the economic dimension of sustainability

  • Energy production at a low price level is now possible: Ongoing developments in solar modules increase efficiency and reduce the price of production even more, making solar power increasingly cost-effective.

  • Once installed, solar panels require very little maintenance: Once solar panels have been installed and generate electricity with maximum efficiency, only a small amount of maintenance is required per year to maintain full functionality.
  • They are silent energy generators: There is absolutely no noise generated by solar panels as they convert the sunlight into usable energy.
  • With solar panels, the company saves billions or even trillions of dollars: Long before global warming threatens society's very existence, it is believed that within the next few decades global warming will cost billions of dollars. Even if one ignores the long-term consequences, it is nevertheless possible to reduce or save the costs that society has to pay with the help of solar energy. See the diagram "Benefit of sustainability for the economy".
  • Solar energy is reliable: The sun's course is extremely constant and reliable. For every place in the world we know the exact times of sunrise and sunset. While clouds are less predictable, experience has taught us how to predict the number of hours of sunshine for different locations. This consistency makes solar energy an extremely reliable source of energy.
  • Solar energy increases security: In addition to the advantage of reliability, the scenario of a monopoly is also impossible, since no one can claim the sun alone. Combined with the simplicity of solar panels, Solar creates a high level of security that the US military has been highlighting for years and that makes it a The main reason for the high level of capital is the flow into the development and installation of solar parks.

Benefits for the social dimension of sustainability

  • Solar energy creates jobs: As an energy source, solar energy creates numerous jobs. The very same investment in solar energy creates 2 to 3 times more new jobs in the solar industry unlike coal and gas.

Benefits for the environmental dimension of sustainability

  • Negligible greenhouse gases: Raw materials from which we generate the majority of our energy - coal and natural gas - produce large quantities of greenhouse gases (coal more than Gas). Wind energy as such does not produce any greenhouse gases, but only through the production, installation and maintenance of turbines small quantities of such gases are generated. On average, however, these are amortised in the first 9 months due to the emission-free operation of the wind turbines and can therefore be neglected.
  • Clean air: Other energy sources produce environmentally harmful substances, damage the environment and thus contribute to global warming, while wind energy is free of emissions.
  • Efficient land use: Although wind farms cover a large area, the actual land use is small, which only has a very limited impact on the original use - be it agricultural or livestock farming.

Benefits for the economic dimension of sustainability

  • Price stability: The price of energy production from fossil fuels and nuclear power is subject to strong fluctuations due to highly fluctuating extraction and transport costs. Wind can compensate such differences, as the price of energy production is calculable and unchanged.
  • Cost-effective power generation: The cost of wind energy fell from almost 40 cents per kWh in the early 1980s to 2.5 - 5.0 cents per kilowatt hour today, depending on wind speeds and the size of the wind farm.
  • Free energy: In contrast to other forms of energy generation, where costs are associated to the transport of raw materials, wind has the advantage of being available on site for power generation, which is also free of charge. Wind is a natural fuel that does not have to be procured or transported, eliminating two major cost factors in energy production.

Benefits for the social dimension of sustainability

  • Energy Independence: Wind turbines diversify our energy portfolio and reduce our dependence on foreign fossil fuel. Wind energy is homegrown electricity, and can help control spikes in fossil fuel cost. Distributed generation facilities, like many community wind projects, provide a safeguard against potential terrorist threats to power plants.
  • Creates Jobs: Wind energy projects create new short and long term jobs. Related employment ranges from meteorologists and surveyors to structural engineers, assembly workers, lawyers, bankers, and technicians. Wind energy creates 30% more jobs than a coal plant and 66% more than a nuclear power plant per unit of energy generated.

Example: Scotland

Renewable energy is already the primary source of energy for Scotland, with wind and hydro making up the bulk of renewables at 62 percent and 29 percent in 2014, respectively. Scotland produces a quarter of the U.K.’s total renewable generation.
Onshore wind is the biggest source of renewable energy in Scotland, but the country also boasts nearly 200 megawatts of offshore wind and hopes one day to be the world leader in tidal power.
