The search for more sustainable forms of energy is gaining momentum around the world. Faced with climate change, pollution and the scarcity of natural resources, the clean energy is emerging as a necessary and promising alternative. But what is clean energy anyway? What are its types, advantages and challenges? And how can it transform our future?
In this article, we'll explore this topic in a simple and straightforward way.
What is clean energy
Clean energy is energy that has little or no negative impact on the environment. Unlike fossil fuels such as coal, oil and natural gas, which release polluting gases and accelerate global warming, clean energy is generated from renewable sources such as the sun, wind and water.
These sources are considered inexhaustible on a human time scale and help preserve the planet for generations to come. In addition, this type of energy is also known as "green energy" or "renewable energy".
How did the concept come about?
The concept of clean energy began to gain prominence in the 1970s, with the oil crisis and increased environmental concern. Over the years, the debate on sustainability and the effects of climate change have led governments, companies and society to start looking for alternative, less polluting sources.
In recent years, as technology has advanced and costs have fallen, it has become more accessible and viable, gaining ground all over the world.
Main sources of clean energy
There are various ways of producing clean energy. Some are more developed, while others are still emerging. Below, we highlight the main sources:
Solar energy
A solar energy is one of the most promising and accessible sources of clean energy. It is generated from sunlight using photovoltaic solar panels that transform solar radiation into electricity.
This technology can be used in homes, businesses and rural areas. Brazil, as a country with high solar incidence throughout the year, has enormous potential for using this source.
Among the main advantages of solar energy are:
1. An abundant and free source
The sun is an inexhaustible source of energy. The amount of solar energy that hits the Earth in one hour is enough to supply the entire world's energy needs for a year.

Other emerging sources
In addition to solar energy, other clean energy sources are also gaining ground:
- Wind power: uses the power of the wind to move turbines and generate electricity.
- Hydroelectric power: harnesses the power of river water to move turbines in power stations.
- Biomass: uses organic waste, such as wood scraps and sugarcane bagasse, to generate heat or electricity.
- Nuclear energy: although controversial, it is considered clean because it does not emit greenhouse gases during energy generation.
Advantages of clean energy
The large-scale adoption of clean energy has a number of notable benefits, both for the environment and for society as a whole. Among the main advantages are:
Reducing pollution
Energy from renewable sources contributes significantly to reducing the emission of polluting gases such as sulphur dioxide, nitrogen oxides and particulate matter, which are responsible for public health problems such as respiratory and cardiovascular diseases. In addition, lower emissions of greenhouse gases, such as carbon dioxide, help to combat climate change and its negative impacts, such as rising global temperatures, melting glaciers and rising sea levels.
Preservation of natural resources
Renewable energy sources such as solar, wind, water and biomass are considered inexhaustible, unlike fossil fuels such as oil, coal and natural gas, which are finite and take millions of years to form. The use of clean energy prevents the depletion of these natural resources, guaranteeing their availability for future generations.
Long-term savings
Although installing clean energy systems can require a considerable initial investment, the costs of operation and maintenance are relatively low, especially when compared to the costs of producing energy from fossil fuels, which are subject to price fluctuations and geopolitical instability. It can provide long-term savings for both consumers and governments.
Job creation
The renewable energy sector is one of the fastest growing in the world, generating millions of direct and indirect jobs in areas such as research and development, equipment manufacturing, system installation and maintenance, consultancy and project management. The transition to a low-carbon economy can boost economic and social development, creating new job and income opportunities.
