A sustainability is a fundamental concept for guaranteeing a balance between human development and the preservation of the planet. It involves practices that harmonize the use of natural resources with the need to protect the environment, ensuring that future generations have access to the same conditions we enjoy today.
Among the most promising solutions for environmental sustainability is the solar energy. This renewable and abundant source reduces dependence on fossil fuels and contributes to reducing environmental impacts. In this article, we will explore the importance of sustainability and how solar energy has become an essential pillar for a better future.
Sustainability today
Planet Earth faces significant challenges that threaten the environmental balance and the quality of human life. Among the main global problems are climate change, o deforestation, a pollution and the depletion of natural resources.
Climate Change: the increase in greenhouse gas emissions intensifies global warming. This causes extreme weather events such as droughts, floods and heatwaves, impacting the lives of millions of people and ecosystems.
Deforestation: the illegal destruction of forests for agriculture, cattle breeding and urban sprawl results in a loss of biodiversity and the release of carbon stored in the vegetation.
Pollution: the contamination of air, water and soil by plastics, chemicals and other pollutants compromises the health of ecosystems and communities.
Depletion of natural resources: the overexploitation of resources such as drinking water and fossil fuels leads to scarcity and conflicts, aggravating food and energy security crises.
For example, it is estimated that without concrete actions, the extraction of natural resources could increase to 60% by 2060putting even more pressure on global ecosystems. On the other hand, dependence on fossil fuels still accounts for two thirds of the world's energy demand, making it difficult to meet climate targets such as the global warming limit of 1.5°C, according to the Federal Government's Climate Change in Brazil Report(Ministry of Science, Technology and Innovation).
Therefore, the transition to more sustainable practices, such as the adoption of renewable energies and the efficient use of resources, is an urgent necessity to ensure a balanced and sustainable future
Renewable energy
When we talk about caring for the environment and curbing climate change, one of the most important steps is decarbonizing the energy matrix. This means gradually replacing the most polluting energy sources with cleaner, more sustainable alternatives.
In Brazil, even though much of our energy comes from renewable sources such as hydroelectric power, we still have a considerable share of greenhouse gas emissions linked to electricity generation. To give you an idea, the energy sector accounts for around 27% of all emissions in the country. This shows how much we still need to invest in greener solutions.
Decarbonizing the energy matrix is not just an environmental issue, it's an opportunity to create jobs, innovate and make access to energy fairer and more efficient.
