Pumped-storage hydroelectricity

Hoover Dam is considered to be one of the must see sights apart from The Strip when one goes to Las Vegas. Apart from being an attraction for tourists to come to see it, also provides enough power to serve 1.3 million people for residents in Arizona, Southern California, and Southern Nevada. From the Dam alone it produces on average 4 billion kilowatt-hours of hydroelectric energy (“Hoover Dam”). Hydropower is being looked at as an safe alternate source of energy. There have been several debates…

Nigeria has one of the lowest electricity generation per capita rate in the world resulting 6 in shortage of power supply and heavy dependence on fossil fuels (79 % of total). At present, 7 only 10% of rural households and 50% of the country’s total population have access to national 8 power grid electricity. Separate researches conducted by Energy Commission of Nigeria and 9 Global Energy Network Institute (GENI) have concluded that 100% stable power supply from 10 renewable energy is possible…

The binding factor in nearly all kinds of power plants is how the power is actually produced: something heats water, turning it into steam, which then turns a turbine that generates electricity. The differentiating factor in the differents forms of power plants is how that water is heated. Nuclear plants fancy splitting atoms, coal plants burn coal, and geothermal plants skip the middle man, let Earth do the heating, and simply reap the benefits. Below the surface of Earth is a layer of rock so…

Renewable Energy and You Every time a light comes on in a house energy is being used. There many different ways to get this energy. Whether it’s from burning fossil fuels or using renewable resources. Most homes get the energy from factories or utility companies that generate it. Majority of these companies use fossil fuels to generate the energy that is then sent to people’s homes. The bad part about this is that harmful chemicals are produced during this process. A way to slow down the release…

OBJECTIVE: The pump is made of pendulum, two-leg lever and cylinder with the piston which pumps the water. Oscillation of the pendulum is maintained by periodical action of the human arm. Oscillation period of the pendulum is twice bigger than the period of the lever oscillation. Piston of the pump has reverse effect on the lever and damps its oscillation. Damping of the lever motion causes damping of the pendulum, but the work of the force damping the pendulum is less than the work of the…

Hydroelectricity is the utilization of flowing water to create electricity, usually through the use of a dam. Wind energy is classified as the use of wind to turn a turbine blade in order to produce electricity (Ellabban et al., 2014). Among all the renewable energies, hydroelectricity is the most widely used as it makes up 85% of the renewable energy market, has a capacity of 970 GW, and produced 3500 TWh of electricity in 2011. This is due mainly to the fact that hydroelectricity produces…

By doing this, the cost of providing hydroelectricity for individuals in Cameroon - who have no energy - will be transferred to the non-profit organizations. The government will then have residents with better healthcare access, eco-friendly energy, and a reduced carbon dioxide footprint. By granting…

The dam we are planning to build will not only help the environment it will slow down global warming and grow more crops for human consumption. This dam can also be used for irrigation purposes like growing crops for humans and animals alike. You can also use this water as clean drinking water. The salmon population will maintain similar to what was before because ninety-seven percent still survive. It will slow down global warming by not having us burn coal for energy creating greenhouse gases…

There are many dams built all over Africa because that is their main source for electric power. While some dams were a success, others were as successful. Because of poor planning, a lot of people had to move and ended up in refugee camps in which the hygiene was very poor and as a result, many diseases spread. Over a thousand wild animals relocated after the water rose in the dams. Because of the droughts in Africa, the supply of electricity had decreased. Malaria is a disease transmitted to…

Hydroelectric energy is made from a turbine that turns falling water into mechanical energy; then that mechanical energy is turned into electric energy. This process helps produce electric energy from the kinetic energy of falling water. How does this process involve chemistry? It first begins with the mechanical energy of the water. Mechanical energy is all the energy that is put upon an object. In the case of the hydroelectric generator, the mechanical energy is made from the position of…
