Energy is at the center of global concerns about climate change. There are several types of renewable energy, some used in different areas for hundreds of years, others developed more recently. They have the potential to reduce energy dependence on fossil fuels, which are the main source of pollution generated by human activities. renewable energies offer viable solutions to protect the environment. They come from natural sources, which are replenished at a higher rate than they are consumed and have a low or zero carbon footprint.
The business environment has become more and more open to the use of these resources, due to the cost advantages and the reduced negative impact on the environment. ISO certification, required by national legislation, guarantees constant actions to reduce energy consumption in production processes and the use of energy from renewable sources.
Top most used renewable energy sources
Renewable energies are also generically called clean energy or green energy, but the reality is that there are some differences between them. Find out which are the most widely used or efficient types of renewable energy:
1. Solar energy
One of the most affordable and popular forms of renewable energy, it uses sunlight to generate electricity or heat through photovoltaic panels or solar collectors.
Advantages:
- Availability: the sun is an inexhaustible source of energy that can be harnessed in almost every region of the globe;
- Environmentally friendly: Solar energy produces no greenhouse gas emissions in the process of collection and transformation into electricity;
- Falling costs: Solar technology is becoming increasingly affordable, with installation and maintenance costs falling.
Disadvantages:
- Weather dependent: The efficiency of solar panels can be affected by weather conditions;
- Area needed: In order to generate large amounts of energy, large areas are required to install the panels.
2. Wind energy
Wind energy uses wind power to generate electricity through wind turbines. It is one of the oldest and most efficient types of renewable energy.
Advantages:
- High efficiency: Modern wind turbines have a very high efficiency of converting the kinetic energy of wind into electricity;
- Once installed, maintenance and operating costs are relatively low.
Disadvantages:
- Visual and noise impact: Wind turbines can visually affect the landscape and produce noise;
- Wind variability: Energy production can be inconsistent due to variations in wind speed.
3. Hydroelectric power
Hydropower is generated by using the force of flowing or falling water to produce electricity. It is one of the most highly developed types of renewable energy.
Advantages:
- Reliability: Hydropower plants can provide a constant source of energy;
- Flexibility: They can be quickly adjusted to meet energy demand.
Disadvantages:
- Environmental impact: Dam construction may affect ecosystems and the natural habitat of certain species of fish, birds or animals;
- Dependence on water sources: Energy production can be affected by droughts or climatic changes that influence the hydrological regime.
In addition to these three types of renewable energy, other clean resources, such as biomass or geothermal sources, have been developed and are being used.
Each of these renewable energy categories offers promising solutions for reducing long-term dependence on fossil fuels and combating climate change. The use of a mix of renewable energy sources and investments in technology and infrastructure are needed to fully exploit the potential of these renewable resources.
For the successful exploitation of these renewable energy resources, environmental specialists provide specific consultancy services in this field, which means either a environmental auditor the inventory of potential sites for investment projects. It also carries out investigations or various types of environmental studies requested by the competent authorities in the process of issuing regulatory documents.
