The Earth is full of abundant resources that we humans use to heat our homes, power cars, produce electricity, and many other activities we perform. We mostly use fossil fuels as the main energy sources for these jobs, however, after centuries of searching for fossil fuels and using them, their supplies are running out because they are a non-renewable resource, which means you will use them all up before they run out . can be replenished. With their supplies running low, we must find alternative resources to replace fossil fuels for electricity and fuel for our transportation. Hydropower is the perfect choice to replace hydropower. Hydroelectricity is an alternative energy source that can be used to power homes. Hydroelectric power comes from a dam or hydroelectric power plant where water is channeled through dam tunnels and the power from the water turns turbines inside the dam. Then the turbines drive the generators inside the power plant, and the generators produce electricity that is sent through a system of transmission lines to which all the major energy sources called the grid are connected, so that everyone in the nation can use them. Like all energies, hydroelectric energy is not all perfect, it has both advantages and disadvantages on an environmental and economic level. The first advantage of hydroelectric energy is that the water used to operate the power plant is provided free of charge by nature, which means that it is a clean resource, and this leads to less pollution and the reduction of greenhouse gas emissions which contribute to global pollution. heating. The second advantage of hydropower is that the cost of hydropower is cheap with a daily cost of only 12 cents, with… half of the paper… flooding land and wildlife habitat. Building dams creates a reservoir that will cover former forest land under water, which could disrupt the food chain in the area. The sixth disadvantage of hydropower is that the amount of electricity produced depends on the speed of the river. Despite all these disadvantages, hydroelectric energy is still the most widely used of all other alternative energy sources and cleaner than fossil fuels. In conclusion, hydropower is a clean energy that will replace fossil fuels once they are exhausted forever. Hydropower provides approximately 20% of the world's electricity needs and approximately 88% of total electricity generated from renewable energy sources. Hydropower is an energy we can trust and has surprising advantages and disadvantages that can be corrected by humans..
