Social, Economic, and Environmental Impacts of Renewable Energy Resources
In the United States and many other countries, most energy sources for doing work are nonrenewable energy sources: Petroleum Hydrocarbon gas liquids Natural gas Coal Nuclear energy.
These energy sources are called nonrenewable because their supplies are limited to the amounts that we can mine or extract from the earth. Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and animals that lived millions of years ago. That is why we also call those energy sources fossil fuels. Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal.
Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split through a process called nuclear fission to create heat and, eventually, electricity.
Scientists think uranium was created billions of years ago when stars formed. The major types or sources of renewable energy are Solar energy from the sun Geothermal energy from heat inside the earth Wind energy Biomass from plants Hydropower from flowing water. They are called renewable energy sources because they are naturally replenished. Day after day, the sun shines, plants grow, wind blows, and rivers flow. Throughout most of human history, biomass from plants was the main energy source, which was burned for heat and to feed animals used for transportation and plowing.
Nonrenewable sources began replacing most of renewable energy use in the United States in the early s, and by the earlys, fossil fuels were the main sources of energy.
Use of biomass for heating homes remained a source of energy but mainly in rural areas and for supplemental heat in urban areas. In the mids, use of biomass and other forms of renewable energy began increasing largely because of incentives for their use, especially for electricity generation.

A non-renewable resource also called a finite resource is a natural resource that cannot be readily replaced by natural means at a quick enough pace to keep up with consumption. The original organic matter, with the aid of heat and pressure, becomes a fuel such as oil or gas. Earth minerals and metal ores , fossil fuels coal , petroleum , natural gas and groundwater in certain aquifers are all considered non-renewable resources, though individual elements are always conserved except in nuclear reactions. Conversely, resources such as timber when harvested sustainably and wind used to power energy conversion systems are considered renewable resources , largely because their localized replenishment can occur within time frames meaningful to humans as well. Earth minerals and metal ores are examples of non-renewable resources. The metals themselves are present in vast amounts in Earth's crust , and their extraction by humans only occurs where they are concentrated by natural geological processes such as heat, pressure, organic activity, weathering and other processes enough to become economically viable to extract.
Local governments can dramatically reduce their carbon footprint by purchasing or directly generating electricity from clean, renewable sources. Using a combination of renewable energy options can help meet local government goals especially in some regions where availability and quality of renewable resources vary. Generating renewable energy on-site using a system or device at the location where the power is used e. Purchasing green power through through renewable energy certificates RECs - also known as green tags, green energy certificates, or tradable renewable certificates — that represent the technology and environmental attributes of electricity generated from renewable resources.
Conventional energy source based on coal, gas, and oil are very much helpful for the improvement in the economy of a country, but on the other hand, some bad impacts of these resources in the environment have bound us to use these resources within some limit and turned our thinking toward the renewable energy resources. The social, environmental, and economical problems can be omitted by use of renewable energy sources, because these resources are considered as environment-friendly, having no or little emission of exhaust and poisonous gases like carbon dioxide, carbon monooxide, sulfur dioxide, etc. Renewable energy is going to be an important source for power generation in near future, because we can use these resources again and again to produce useful energy. Wind power generation is considered as having lowest water consumption, lowest relative greenhouse gas emission, and most favorable social impacts. It is considered as one of the most sustainable renewable energy sources, followed by hydropower, photovoltaic, and then geothermal.
Jump to navigation. Renewable power is booming , as innovation brings down costs and starts to deliver on the promise of a clean energy future. American solar and wind generation are breaking records and being integrated into the national electricity grid without compromising reliability. Biomass and large hydroelectric dams create difficult tradeoffs when considering the impact on wildlife, climate change, and other issues.
Renewable Energy: The Clean Facts
Many people nowadays are turning to renewable energy for their power. They know that renewables are a necessary alternative to fossil fuels and other non renewables, which will eventually run out. Most are also aware that renewable energy is kinder to the planet and society. But exactly how does non renewable energy affect the environment?
The post you are on right now was written in Please see this updated article with more current information, including new sections on climate change and nuclear power. There are nine major areas of energy resources. They fall into two categories: nonrenewable and renewable.
Production, Reserves, and Consumption
Renewable and nonrenewable resources are energy sources that human society uses to function on a daily basis. The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. This means that nonrenewable resources are limited in supply and cannot be used sustainably. There are four major types of nonrenewable resources: oil, natural gas, coal , and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. They are found in underground layers of rock and sediment.
The is defines as the sources of energy which are produced continuously in nature and are essentially inexhaustible at least in the time frame of human societies.
As we noted in Chapter 12, the reserves of non-renewable resources are inexorably diminished as they are extracted from the environment and used in the human economy. This is because non-renewable resources are finite in quantity and their stocks do not regenerate after they are mined. Note that the word reserve has a specific meaning here — it is used to denote a known amount of material that can be economically recovered from the environment that is, while making a profit. Of course, continuing exploration may discover previously unknown deposits of non-renewable resources.

Неплохо, но есть одно. Он не пользовался своими обычными почтовыми ящиками - ни домашним, ни служебными. Он бывал в Университете Досися и использовал их главный компьютер. Очевидно, там у него был адрес, который он сумел утаить. Это хорошо защищенный почтовый ящик, и мне лишь случайно удалось на него наткнуться.
