The first international agreement on fighting climate change was the Kyoto Protocol , adopted in One caveat is that the alternatives require ample lead time to be put into place.
That process has begun slowly. Wind power generated about 6. About 1. In the U. By the end of , research firm IHS Markit predicts that all-electric car sales would surpass 3.
Nonrenewable resources are derived from the Earth— in a finite supply that can take billions of years to replenish.
Historically, many nonrenewables have been relatively cheap to extract. But as their supply continues to diminish, the cost of this extraction may rise in price, leading customers to use alternative sources, such as solar and wind energy.
Among the most common examples of natural resources are crude oil, coal, uranium, and mineral sources such as gold. One subset of nonrenewable resources includes crude oil and natural gas. Both of these substances are made out of organic carbon material, depending on the form it takes after heating and compressing over time.
Another form of nonrenewables is minerals, which include gold, silver, and iron. Unlike crude oil and natural gas, these are quite difficult and expensive to extract. Meanwhile, different types of groundwater are nonrenewables when they do not replenish at their draining speed.
Since nonrenewables, by definition, will diminish in supply over time, the law of supply and demand suggests that their price will continue to rise. Renewables, by contrast, have an infinite supply. However, at the same time, the cost and time required to establish them will be lengthy. More recently, demand for renewables has grown in tandem with governmental incentives, with many of their costs decreasing over time.
Solar energy is one prime example of this trend. Department of Energy. Energy Information Administration. Pew Research Center. IHS Markit. Renewable Energy. Your Privacy Rights.

Rising costs: As just a few countries hold a large number of fossil fuels, fuel prices can rise without warning.
Health risks to workers: Mining for coal or drilling for oil can be very dangerous, resulting in a large number of diseases, injuries, and deaths every year. Teacher's Toolkit Take this to the classroom! Curriculum ready content. Unit Plan Law of Conservation of Energy. Year Year 7.
Lesson 3 - 4. Year 6. Lesson 1. Lesson 2 - 4. Crude oil is a liquid fuel fossil fuel that is used mostly to produce gasoline and diesel fuel for vehicles, and for the manufacturing of plastics. Natural gas is widely used for cooking and for heating homes. Natural gas can be pumped out through the same wells used for extracting crude oil. Coal is a solid fossil fuel that is used for heating homes and generating power plants.
It is found in fossilized swamps that have been buried beneath layers of sediment. Since coal is solid, it cannot be extracted in the same manner as crude oil or natural gas; it must be dug up from the ground. Nuclear energy comes from radioactive elements, mainly uranium , which is extracted from mined ore and then refined into fuel. Unfortunately, human society is—for the time being—dependent on nonrenewable resources as its primary source of energy.
Approximately 80 percent of the total amount of energy used globally each year comes from fossil fuels.
We depend on fossil fuels because they are energy-rich and relatively cheap to process. But a major problem with fossil fuels, aside from their being in limited supply, is that burning them releases carbon dioxide into the atmosphere.
Rising levels of heat-trapping carbon dioxide in the atmosphere is the main cause of global warming. Alternative energy sources, such as wind and solar energy, are a possible solution to the depletion of nonrenewable sources.
Both of these clean energy sources are available in unlimited supply. Also called diesel oil and diesel fuel. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit.
Natural gas is found as a component of petroleum, as well as in gaseous deposits separate from petroleum. Both of these energy sources release carbon dioxide into the atmosphere and natural gas also releases methane due to leaks in the process of extracting it.
The extraction of oil fuel has caused major damage to marine ecosystems from oil rig malfunctions and spills in our oceans and from runoff caused by extraction on land. Steel and aluminum are metals that are extracted from the earth and are nonrenewable.
These resources are part of our daily lives, whether they make up our appliances or manufacturing equipment or enable the agricultural processes that feed our planet to work.
Aluminum and iron ore, a main component of steel, are acquired from open-pit mining which is detrimental to the earth and ecosystems, resulting in pollutant-filled runoff and climate problems. The extraction of rare earth metals is complicated as these elemental structures are connected with other minerals. Rare earth metals are an important nonrenewable resource that is an essential component in all our electronic and high-tech devices.
The extraction of these rare earth metals from the earth is harmful to our environment and our extreme dependence on them as nonrenewable resources is a cause for concern.
It is time to start studying and exploring renewable solutions to create our high-tech gadgets. Phosphates, which come from the element phosphorus, are an extremely important resource in our daily lives. This resource is so important in conventional agriculture, much of farming and cultivating is actually dependent on phosphates in fertilizer to feed our plants and animals.
Phosphates are mined from minerals inside of the earth and refined and purified for its application in many widespread products. However, continued massive extraction of this nonrenewable resource is not sustainable, as Julia Rosen notes in The Atlantic. Alas, there are renewable solutions that cause exponentially less harm to the environment and could enable a cleaner future.
We are able to harness energy that fuels our environment with renewable resources and methods. Renewable resources, such as solar and wind, will never run out. These resources are preferable because we know their supply will not diminish.
