Limited Energy Resources Finite resources are essential to energy production because they can produce energy more efficiently and abundantly. Non-renewable resources cannot be replaced. Oil is perhaps our most commonly used source of energy, however it is not renewable, so our supply of oil is limited. Oil creates energy by burning and trapping gas in deposits. The United States hit peak oil around 1970, while the world hit peak oil around 2000. The term “peak oil” does not mean we are running out of oil, it simply means we are running out of oil at cheap. There are different alternatives to the use of oil, each with its pros and cons. Coal, nuclear, hydrogen, biofuels, wind and solar are all energy sources that can and are being used to slow the use of our precious oil. That said, to produce the equivalent amount of energy supplied by oil in one year (33 billion barrels of oil) it would take: 200 Three Gorges dams, 2,600 nuclear power plants, 5,200 coal plants, 1,642,500 wind turbines and 4,562. 500,000 solar systems. Panels. This represents only 37% of the world's energy. We tend to use oil more often because it is the most energy dense oil, easiest to store, and is extremely versatile. The world's focus on using non-renewable energy resources, rather than renewable resources, is problematic because if the world uses up most of its resources we will not be able to replenish it in our current lifetime. The supply of non-renewable resources decreases while demand increases as our population grows. Due to decreasing supply and increasing demand, the prices of these resources will increase dramatically. Oil, for example, will become more expensive to drill because we have to drill for... half the paper... other diseases such as tuberculosis can significantly affect the economy when it comes to decreasing production rates.TDR is an organization which specifically aims to end the diseases of poverty. The United Nations sponsors the foundation by giving them money to provide vaccinations and money for research into the ongoing problem. The United Nations and its various technical agencies therefore play a vital role in promoting access to healthcare. Water scarcityOnly 2% of our globe's water is fresh. Of that 2% only 0.37% is drinkable. Water scarcity is one of the biggest problems in our world because water is a non-renewable resource. We consume 900 million gallons every day for domestic use, transportation, energy and consumption of physical goods.
