Hydroelectric Power – Cleaner, Cheaper and Safer Than Fossil Fuels

Hydroelectric power, also known as hydroelectricity, captures the energy of flowing water to transform it into electricity. It’s one of the world’s largest sources of renewable, emissions-free electricity sources.

Hydropower can offer clean, reliable energy to homes and businesses around the globe. Not only does it help communities reduce their carbon footprints, save money, and foster a healthy environment, but it’s also an efficient source of production.

1. It’s an Underutilized Resource for a Sustainable Future

Hydroelectric power is an abundant and sustainable renewable source of energy that empowers communities to meet their electricity needs and enhance quality of life. Plus, it’s cleaner, cheaper and safer than other forms of energy.

Hydropower differs from coal, oil, and nuclear fuels in that it creates no solid wastes like dredged material or waterborne debris and does not need significant land for storage.

Renewable resources like hydroelectricity and rainfall replenish themselves naturally. It’s one of the most efficient forms of energy production, cutting carbon emissions in half compared to fossil-fuel based power sources.

However, large dams used for hydropower generation may have negative consequences on social and environmental communities as they destroy habitats for wildlife. Furthermore, such dams can degrade river quality by impeding fish migration.

2. It’s Cleaner

Hydroelectric power is one of the cleanest forms of energy available. Compared to fossil fuels, which emit large amounts of carbon dioxide and other greenhouse gases, hydroelectric power produces far fewer emissions.

Hydropower plants transform water into electricity by funneling it down a pipe or tunnel and spinning a turbine, which then spins a generator. These systems can be found on rivers and lakes around the world.

Many plants utilize pumped storage, which stores energy for future use by pumping water uphill into a reservoir. This system is commonly referred to as “pumped storage hydropower.”

Hydroelectric plants tend to generate less emissions than other energy sources, like coal and natural gas, due to the lower amount of carbon dioxide and methane produced. However, these emissions can vary considerably due to factors like reservoir temperature, water levels in the upstream watershed, and environmental conditions surrounding the dam.

3. It’s Cheaper

Hydroelectric power is more cost-effective than other forms of energy like coal and natural gas, as its price does not fluctuate as drastically.

Hydropower plants generate electricity by channeling water through a pipe that turns a turbine and rotates a generator. They use water from rivers and lakes, which is an abundant renewable resource.

They provide a flexible source of energy as they can quickly scale up or down to meet consumer needs. This makes them an ideal complement to variable renewables like wind and solar.

Energy can even be stored in large “water batteries.” This technology is particularly advantageous as it provides electricity at night when wind and sun don’t produce enough power. Energy storage plays a crucial role in creating a sustainable future.

4. It’s Better for the Environment

Hydroelectric power is a climate-friendly energy source that produces electricity without emitting air pollutants or greenhouse gases. Furthermore, it reduces acid rain and smog – two major contributors to global warming – by eliminating them from the equation.

Thus, hydroelectric projects are often built in areas with little or no fossil fuel resources and can replace power generated from coal or oil. This helps combat climate-related pollution while stabilizing local ecosystems.

Dams and reservoirs can have a detrimental effect on river habitats, altering water temperature and nutrient concentrations. They also alter water quality by causing silting up of rivers and scouring away their bedrock.

According to a study of over 1,400 dams worldwide, dams can emit more carbon dioxide and methane than previously believed. Droughts in the American West have caused dams to produce less electricity, and scientists speculate that this switch away from hydropower could result in an increase in carbon emissions.
