Non-Renewable Resource Issues
Before we get started on renewable energies let's take a look at non-renewable energy. These are resources found under the ground: coal, oil and gas. Trees breathe in carbon dioxide and store the carbon in their trunks.
Millions of years ago many trees sank into the swampy ground where they had been growing and disappeared, taking the carbon they had absorbed with them. The same thing happened with oil and gas except these were originally tiny sea creatures which stored the carbon in their bodies and shells and took it with them when they died and their bodies got buried.
Without fossil fuels, many countries would not have been able to develop and industrialise to give us the lifestyles which we enjoy today. Now more countries such as China and India are developing at a very fast rate and their energy needs are soaring. The trouble is that when we burn fossil fuels to make electricity, run our cars and for many other uses the carbon is released back into the atmosphere where it contributes to the greenhouse effect.
See our 'Greenhouse Effect' video in the resources section below. Not only that but breathing in this pollution is not good for our health, especially in cities where they have a large number of cars such as Mexico city. But there are still coal fired power stations being built around the world to meet our rising demand for energy to run all of our gadgets.
Oil - approximately 56 years Gas: approximately 55 years Coal: approximately years. As fossils fuels become more expensive and harder to find, renewable energy will become cheaper as technology improves and the equipment is made on a larger scale. Renewable Energy.

All the solid fuels fossil energy and mineral commodities we use come out of the Earth. Modern society is increasingly dependent on mineral and fossil energy sources. They differ in availability, cost of production, and geographical distribution. Even if solid fuels, fossil energy resources and mineral commodities are non-renewable, the extracted metals can to a large extent be recycled and used again and again. Although the stock of these secondary resources and their use increases, the world still needs and will continue to need primary mineral resources for the foreseeable future. Growing demands have begun to restrict availability of these resources. The Earth is not running out of critical mineral resources — at least for the near future — but the ability to explore and extract these resources is being restricted in many regions by competing land use, as well as political and environmental issues.
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? Non renewables can often pollute the environment and cause other damage, making the switch to renewable energy even more important. Non renewable energy typically releases carbon dioxide, methane, and other gasses into the atmosphere. These are called greenhouse gasses because, similar to the way a greenhouse creates a warm atmosphere for plants, the gasses create a warming effect across the planet.
Carbon dioxide is produced from the burning of fossil fuels like coal and gas. Non-renewable energy is a source of energy that will eventually run out. Most sources of non-renewable energy are fossil fuels , such as coal, gas, and oil. These natural resources are a major source of power for a vast amount of industries — however, there are numerous downsides to non-renewable energy, including their negative environmental impact and the fact they are in limited supply. Coal comes from the remains of plants that died hundreds of millions of years ago. It has the highest level of carbon of all fossil fuels. Oil — also known as petroleum — can be extracted and refined in order to make products such as gasoline, diesel, and jet fuel.
Types of renewable energy
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. If that happens, there is an increase in the known reserves of the resource.
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.

Вся ложь Танкадо о невскрываемом алгоритме… обещание выставить его на аукцион - все это было игрой, мистификацией. Танкадо спровоцировал АНБ на отслеживание его электронной почты, заставил поверить, что у него есть партнер, заставил скачать очень опасный файл. - Линейная мутация… - еле выдавил Стратмор. - Я знаю. Коммандер медленно поднял голову.
Беккер замолчал. Он опять перегнул палку. Его план не сработал.
Эти слова буквально преследовали. Она попыталась выбросить их из головы.
