Environmentally friendly energy from renewable sources

What are renewable energies? Environmentally friendly energy is produced from renewable energy sources.

In most of Europe country, alternative energies come primarily from wind and hydroelectric power, and solar energy and geothermal energy are also increasingly being used.

Biomass is also gaining in importance when it comes to energy from renewable sources.

Legal priority for alternative energies

Alternative energies are promoted in Europe through a series of legislative measures. This is done for reasons of environmental protection, but also because conventional energy sources are finite, so will eventually be used up.

The Renewable Energy Act and other regulations should ensure that by 2020 the share of clean energy in total energy consumption will be 20%. The Renewable Energy Act prescribed from the outset minimum prices at which grid operators must take clean energy. These additional costs are allocated to consumers.

There have been a number of changes since the introduction of the EEG. The basic idea of ​​becoming less dependent on fossil fuels through renewable energies and, above all, counteracting climate change, still applies to a greater extent.

Pros and cons

The advantages and disadvantages of renewable energies are repeatedly discussed, often in connection with the question of nuclear power yes or no.

It will be discussed whether energy demand, especially in industry, can be adequately covered by alternative energy at competitive prices.

However, energy from renewable sources enjoys a large and increasing acceptance among the population. The majority of consumers are quite willing to pay higher prices for clean energy.

Electricity from renewable energies

However, higher prices for alternative energy, primarily renewable electricity, could soon be a thing of the past.

The costs of producing green energy are already falling, while the cost of traditional forms of energy tends to increase. In the longer term, the current low oil prices and gas prices are not changing anything either. Technological improvements in clean energy production will further reduce their costs in the future.

Already today, alternative energy, eg. As green electricity and biogas, not be expensive. There are offers that are cheaper than the electricity of local primary suppliers.

With energy computers for the best deal

Comparison portals on the Internet offer free energy calculator with filter functions for green electricity and biogas. They can be used to compare suppliers who only offer energy from renewable sources.
Consumers can find the cheapest alternative energy offer among many fares and often switch online to the new green energy provider in one go.

Benefits of Alternative Energy – Detailed Review

What are renewable energies

Renewable energies or renewable energies are derived from energy sources that can not be consumed by their use or that renew themselves at short notice.

In contrast, fossil fuels are consumed by their use as an energy source at some point. Renewable energy can be electricity, heat or fuel.

Environmentally friendly energy is generated mainly from wind energy, hydropower, solar energy, geothermal energy and tidal energy. Another possibility is biomass (biogas, biofuel) obtained from renewable raw materials.

In Europe, energy from renewable sources is given priority over fossil fuels.

One reason is the increased exposure of pollutants to the environment (CO²), another is the finite nature of fossil fuels, which is currently not in sight.

High acceptance for environmentally friendly energy

At present renewable energy is often even more expensive than energy from other sources of energy. However, over the last 20 years, costs have fallen by an average of 50%, while those for energy from other sources have tended to increase significantly.

By mass production and technology advances, the costs should be reduced significantly by 2020 again.

Renewable energy is very popular among the population. According to older surveys, 77% of Europeans want to use renewable energies, even if this is associated with price increases. 85% of Europeans believe that renewable energy is the energy carrier of the future.

Renewable energy pros and cons

Renewable energy pro and con, this topic is often discussed violently. One point is certainly the cost of renewable energy.

At present, environmentally friendly energy is often even more expensive than energy from fossil fuels or from nuclear power plants.

The Renewable Energy Act provides for the statutory redistribution of prices to the end consumer, which in turn regularly increases electricity prices. But that can change quickly.

Even today, it does not have to be more expensive to use electricity only partially, or at least partially, from renewable energy sources, when consumers use a cost-of-electricity comparison to find the cheapest tariff for their region.

Crisis-safe energy

An advantage of all regenerative energies is that they are ” crisis-proof ” because the energy sources used are all located in land.

The oil tap can be turned off in political crises, with domestically produced energy, eg. B. from the sun, wind and water, this is not possible.

In addition to the benefits for the environment, it is therefore a big plus of renewable energies that they make the energy supply of producer states independent.

Benefits of Alternative Energy – Sources

Solar energy:

The solar energy is free, and there are no disposal problems. Investments for the construction of the plants remain in Europe.

Disadvantages are the weather-dependent time, the low storage capacity and required by current technology large-scale facilities.

Hydropower:

Advantages are the simple construction and the long life of the hydroelectric power plants. They can be used decentrally and are considered to be effective generators worldwide with low costs and a high level of security of supply. 20% of the world’s electricity comes from hydroelectric power plants.

The main drawback: An additional caloric power plant is required because hydropower is of limited use in winter.

Wind power:

Advantages – Wind power is clean and renewable, and comparatively cheap. Disadvantages – the littering of the windmills into the landscape, sometimes referred to as the clearing system, negatively changes the landscape. Sometimes negative effects on the environment are feared (hazards in bird catchment areas).

In some Europe countries, there are only a few regions with favorable wind conditions. Wind can not be stored, but must be converted directly into electricity.

Even huge wind turbines can not deliver the same performance as a modern power plant.

Biogas plants:

Advantages – the energy source for biogas is renewed in rapid cycles, the energy production is CO² neutral and methane can be used as fuel.

Disadvantages – high investment, emergence of monocultures (corn) on large areas.

Other energy sources are being developed

Plants for the production of renewable energy are often (with the exception of hydropower plants) at the beginning of their technological development.

This is especially true for solar energy. New possibilities of energy generation are discussed and already implemented, such as the use of ocean currents and wave energy.

What is certain is that even in a few years’ time you may be discussing the pros and cons of renewable energy in a completely different way than it is now.
