Natural Resources

A:

Solar energy produces electricity by generating copious amounts of heat, which is channeled through electrical conductors and transformed into electrical power. Solar heat collectors, cooling towers and photovoltaic panels are all types of energy systems that use solar energy. Heat collectors and panels sit on building roofs and over parking lots, and they are strategically placed facing south, where the sun shines with the most power.

  • How is coal extracted?

    Q: How is coal extracted?

    A: The two main methods used for coal extraction are surface mining and underground mining. The methods used to extract coal depend on the geology of the coal deposits. According to Energy Trends Insider, the amount of coal produced by one miner in one hour has more than tripled since 1978 because of improvements in mining technology and the growth in surface mining.

  • Will we ever run out of crude oil?

    Q: Will we ever run out of crude oil?

    A: Oil is a nonrenewable resource, which is available only in finite quantities, and it will eventually become uneconomical to extract. New technologies, such as hydraulic fracturing, have delayed that point for several decades, but the total volume of oil is not increasing, according to the U.S. Department of Energy.

  • What are the causes of resource depletion?

    Q: What are the causes of resource depletion?

    A: Overconsumption, or people consuming resources faster than they can be replenished, is the main cause of resource depletion. Overpopulation, industrial and technological development, erosion, deforestation, over-fishing, irrigation, mining and pollution all contribute to the problem as well.

  • How is crude oil turned into plastic?

    Q: How is crude oil turned into plastic?

    A: According to PlasticsEurope, a multinational plastics-industry trade commission, crude oil is distilled into fractions, which are smaller groups of the components that make up oil; some of these fractions are discarded for other purposes, while the ones that are used to make plastics are then further processed. The main fraction of oil that is used for plastic production is known as naphtha.

  • What is the difference between a forest and a wood?

    Q: What is the difference between a forest and a wood?

    A: Woods and forests both have natural areas filled with trees, but woods are smaller and have fewer kinds of plants and animals. Forests have lots of shade because trees grow closely together in an area with a high density of trees. On the other hand, woods have plenty of sunlight because they have less vegetation.

  • How do oil wells work?

    Q: How do oil wells work?

    A: According to San Joaquin Valley Geology, while some oil wells produce a flow purely from the natural pressure of the petroleum deposit, most require a physical pump in order to bring the oil to the surface for harvesting. In most cases, this is a pumping jack, a device that resembles a nodding horse's head.

  • How long will nuclear energy last?

    Q: How long will nuclear energy last?

    A: Scientific American notes that the world's uranium supply, the element used to create nuclear energy, can operate nuclear reactors for 200 years or more at stable consumption levels. Each nuclear reactor requires the use of low-enriched uranium fuel to create electricity. It is estimated that nuclear plants worldwide use approximately 70,000 metric tons of uranium to produce 2.8 trillion kilowatt-hours of electricity each year.
