Essays on Hydropower

In essence, the N.W electric power cooperation is a unit that maintains 130 substations, which transmit power to more than 74000 members. However, climate change has led to the reduction of water supplies that has resulted in a decrease in the production of hydropower. Primarily hydropower is important because it lowers the cost of electricity. Low supply of hydro power means that the government will have to use natural gas in the production electricity, which is expensive. Notably, a significant part of the population is dependent on the salmon recovery. It is a source of income to its workers. ...

The hydrodynamic power is the result of the transformation of the potential energy of water, that is, a column or height difference of water that moves a primary machine that generates mechanical energy. The mechanical energy later is transformed in electricity, thanks to the use of a generator.

Main components of the hydroelectric plants

A large dam to store water, provide a constant flow of water and accumulate potential energy in the form of hydraulic load. A large capacity of the dam gives reliability to the hydroelectric plant with a guarantee of a constant flow of water to the turbines. An abduction which is a ...

Executive Project Summary – Malawi Wind Farm

Market Summary Malawi has an electricity production of 2,180 MWh and a consumption of 2,027 MWh. The 95% of the electricity generation comes from hydroelectric sources giving to the high country risks of supply shortages in adverse weather conditions when the water level of the hydroelectric plants is below the technical specifications of the turbines. The country has no other important source of energy having the country the necessity to develop new energy sources different to the hydroelectricity. The surroundings of the Malawi Lake develop winds over the 10 m/s average per year, opening the opportunity to ...

Introduction

A dam is a structure specifically constructed to obstruct the flow of moving water, and by extension raising the water level. Dams are built for various purposes, such as a means of flood control, water storage, and a source of hydroelectric power, specifically hydroelectric ones. Some dams are also used in transportation and inland navigation by acting as bridges that connect one side of a body of water to the next. In other words, dams can have many benefits for a developing society. Because of their perceived benefits, many dams have been built all over the world—at least ...

Introduction

The concept of sustainable development was first introduced in 1987 by the United Nations as part of the Report of the World Commission on Environment and Development, in which it was stated that sustainable development implies “meeting the needs of the present without compromising the ability of future generations to meet their own needs” (United Nations General Assembly, 1987). The World Conservation Strategy published in 1980 served as prelude to the conception of this notion, as the UN recognized the importance of minimizing the impact of human activity over the earth’s ecosystems and adopting models inclined towards sustainability ...

Renewable Energy Capacity Country Data

The primary sources of renewable energy for each of the three countries are indicated as follows; Argentina- hydropower Bolivia- hydropower Chile- hydropower In Bolivia, solid biomass had the greatest increase in the generation capacity compared to the other sources of renewable energy. The capacity increase from 16 in 2006 to 52 in 2015. In Chile, there was significant increase in the generation capacity of almost all the energy sources. However, hydropower showed the largest increase in the energy generation capacity between the year 2006 and 2015. The capacity increased from 5093 to 6320 between the years.

Implications of Erecting Additional Transmission Lines

Introduction Auckland is one of the regions in New Zealand. Auckland does not have many power generation sites like the other regions in New Zealand. However, the demand characteristics for Auckland are still high and are projected to increase due to population growth and economic development. Given that many of the energy production sites have been developed and the development of the remaining sites faces opposition from environmental groups, the viable options for easing the supply issues in Auckland include the development of renewable energy sources such as wind and solar energy, the optimization of the current transmission network ...

Fossil fuels refer to those sources of energies which are underneath the earth surface as a result of the decomposition of the dead plant and animal remains. They include coal, oil, natural gas and others. The excessive use of these fuels led to diverse impacts on the natural environment, which can be seen through increasing rate of global warming. For that reason, the paper, therefore, aims at coming up with different alternatives which will help in stopping the use of fossil fuels in Japan. The plan has been developed to assist the islands which are commonly affected by the ...

The Name of the Class

In recent years, the Earth’s climate varies considerably: some countries suffer from heat waves, the others from too harsh and snowy winters, unusual for these places. Environmentalists talk about global climate change, which includes an increase in mean annual temperature, causing the melting of glaciers, and rising sea levels. In addition to warming, there is also imbalance of natural systems, which leads to changes in rainfall patterns, temperature anomalies and the increased frequency of extreme events such as hurricanes, floods and droughts (Biello, 2016). According to scientists, humanity cannot fully prevent climate change. But the international community is ...

The problem of water resources of the Mekong River threatens to escalate into a serious conflict between China and several Southeast Asian countries. The origins of the Mekong, which occupies the 13th place among the longest rivers in the world (about 4350 km), are located on the Tibetan Plateau. The Mekong flows through China (Tibet Autonomous Region and Yunnan Province), Myanmar, Laos, Thailand, Cambodia and Vietnam. China is already having on the Mekong (China calls it the Lancang River) two operating hydroelectric power stations and at the beginning of September 2012 announced the launch of the third one called ...

According to the data collected in 2013, the world energy consumption was segregated into various power sources such as 31.1% from oil reserves, 28.9% from coals, 21.4% from natural gases, 10.2% from biomass and wastes, 4.8% from nuclear sources, 2.4% from hydro energy and remaining 1.2% from other renewable sources. The most common form of energy used in industrial and household purpose was oil, coal and natural gas (Lawton, 2014). These resources such as coal, oil, and natural gas are natural reserves which are depleting due to extensive extraction over time. Coal is one of the most burned and ...
