Introduction
Hydropower or renewable energy is one of the cleanest sources of electricity in the world. It can be used to generate electricity in two ways: Hydroelectricity and tidal power. The Government has set the target of meeting 15% of its annual energy needs from renewable sources by 2020. Renewable energy sources such as hydroelectricity, wind power and solar power have many advantages over fossil fuels. Fossil fuels are a non-renewable source of energy that takes millions of years to form. It is also responsible for global warming and other environmental problems like ozone depletion, acid rain and air pollution
Hydropower or renewable energy is one of the cleanest sources of electricity in the world.
Hydropower or renewable energy is one of the cleanest sources of electricity in the world. It is an environment friendly, non-polluting and carbon neutral source of power generation. Hydropower does not produce any harmful gases like sulfur dioxide or nitrous oxide (which are both greenhouse gases) during its operation. The only emission that comes out from this process is water vapor which is harmless to environment as well as human beings.
The main advantage of hydroelectricity over other fossil fuels is that once you build a dam on river flow then you can use it for producing electricity anytime throughout year without any interruption what so ever because water flows continuously at all times even during winter season when temperatures drop below freezing point due to snowfall over Himalayan Mountains where most dams lie located near their foothills like Bhakra Nangal Dam built on Satluj River near Chandigarh city in Punjab state India where temperature drops below zero degrees Celsius during January month each year but still there remains enough water flow through turbines installed under dams’ bottom walls inside tunnels bored through mountainside rock formations where turbines rotate with force generated by velocity difference between fast flowing currents above them versus slower moving ones below them; thus generating electricity without any problem whatsoever!
It can be used to generate electricity in two ways: Hydroelectricity and tidal power.
Hydropower is the generation of electricity from the energy of moving water. It can be used to generate electricity in two ways: hydroelectricity and tidal power.
Tidal power is produced from the energy of moving water, like hydroelectricity, but it’s generated by tides rather than rivers or streams. In other words, instead of dams on a river blocking its flow and creating a reservoir behind them where that water can be held back until needed for generating electricity (like what happens at Hoover Dam), we’d build dams on beaches so that as tides rise and fall they’ll drive turbines connected directly to generators above ground level which will produce electricity every time there’s an incoming wave or outgoing one – depending upon where exactly you’ve placed your tidal dam(s).

The Government has set the target of meeting 15% of its annual energy needs from renewable sources by 2020. This means that by 2020, the UK will be using more than three times what it is currently using.
The government has also set a target of reducing carbon emissions by 80% by 2050. This would be an enormous reduction compared to what we’re doing now, which is only about 5%.
Renewable energy sources such as hydroelectricity, wind power and solar power have many advantages over fossil fuels.
Renewable energy sources such as hydroelectricity, wind power and solar power have many advantages over fossil fuels. First, they’re not as expensive; you can expect to pay $0.10 per kilowatt-hour (kWh) with renewable energy compared to $0.08 per kWh for traditional power sources like coal or natural gas. Second, these are cleaner and more environmentally friendly than fossil fuels–they don’t produce carbon dioxide emissions or other pollutants that contribute to global warming when burned by humans for electricity generation purposes. Finally, because all three of these forms of renewable energy are renewable themselves (meaning they can be used over and over again), you’ll never run out!
Fossil fuels are a non-renewable source of energy that takes millions of years to form.
Fossil fuels are a non-renewable source of energy that takes millions of years to form. They’re formed from the remains of plants and animals, so they’re essentially “buried” under layers of earth. Coal, oil and natural gas are all examples of fossil fuels.
Because these types of fuel take so long to form naturally, we’re not going to run out anytime soon–but it does mean that once we use up our reserves, there won’t be any left for future generations (or aliens). In order to keep using them today, we have to find new ways to mine them from underground deposits at faster rates than before–which can be dangerous for workers in mines or refineries and harmful for our environment overall because these processes produce greenhouse gases like carbon dioxide (CO2) or methane which contribute greatly towards climate change
It is also responsible for global warming and other environmental problems like ozone depletion, acid rain and air pollution.
Hydropower is not a perfect source of energy. It is also responsible for global warming and other environmental problems like ozone depletion, acid rain and air pollution. The building of dams has led to the displacement of local communities as well as extinction of some species of plants and animals that depend on the flooded areas for breeding or food supply.
Water is an important commodity around the world and we have only one source from which we can take fresh water – lakes, rivers, streams and ground water.
Water is an important commodity around the world and we have only one source from which we can take fresh water – lakes, rivers, streams and ground water. Water is a renewable resource that can be renewed by precipitation or by natural processes such as evaporation or transpiration (the release of moisture through plants). However, it is also a limited resource because it cannot be created or destroyed; it only changes state between liquid and vapor in response to changes in temperature or pressure.
Water plays an essential role in all human activities: agriculture; industry; food production; health care facilities etc…
Like fossil fuels, hydroelectricity also has some disadvantages too – If a dam breaks then millions of people downstream would be affected immediately!

- Disadvantages:
- Dams have to be built on rivers and this can affect the environment in the area where it’s built. The building process can also cause problems for local wildlife. In fact, many environmentalists are opposed to new dams because they think it will damage nature further and make climate change worse as well as affecting people living nearby who may lose their homes due to flooding caused by increased water levels behind the dam wall (this happened in Brazil recently).
- Advantages: Hydroelectricity is a renewable source of energy which means that we don’t need to keep using up fossil fuels like coal or gas because there isn’t enough left anyway! It also produces less carbon dioxide emissions than other types
When considering building a dam for your hydroelectric project, you should make sure that it doesn’t impact on wildlife or local communities downstream
When considering building a dam for your hydroelectric project, you should make sure that it doesn’t impact on wildlife or local communities downstream.
A good way to do this is by building the dam in such a way that it doesn’t impact on the environment or local communities. For example, if you’re building your dam with concrete, then you can use steel rebar instead of regular rebar so that there’s less waste material produced during construction (and therefore less impact on nature).
Conclusion
Hydropower is a great way to produce clean electricity and it has many advantages over fossil fuels. But it also has some disadvantages – for example, if the dam breaks then millions of people downstream would be affected immediately! When considering building a dam for your hydroelectric project, you should make sure that it doesn’t impact on wildlife or local communities downstream.
