How Hydroelectric Dams Effect Environment

Energy is a big part of our lives. After all, we use it for everything from working, heating, traveling, and more. But the question that remains is where does all this energy come from? Nowadays, most of the energy we consume comes from fossil fuels that include natural gas, coal, and oil. However, part of our energy also comes from nuclear, renewable s, and biomass.Even though fossil fuels are still the primary source of our energy, the truth is that its becoming more costly to pump not to mention the fact that it affects the environment in multiple ways. Some of these effects include oil spills, acid rain, degradation of air quality, and the one that keeps being mentioned all the time, global warming.One of the things that most people do not know or do not realize is that fossil fuels are scarce resources, meaning they will end. And the estimation date for this to happen is somewhere within the next 50 to 100 years.But the fossil fuels are not the only kind of energy that has problems.

The nuclear energy also has its share, Some of them include nuclear radiation hazards and dangerous radioactive waste.Based on these facts, it is not a very big surprise that there has been an increase in the investments in renewable energies such as geothermal, solar, the wind, and hydro power of course. From these four, the oldest and the most used one is the hydro power.Hydro power is the largest source of electricity in the entire world (more than 20%) and for some countries like Paraguay, Venezuela Switzerland, Brazil, New Zealand, and Canada -, this is how they generate most of their electricity.
