What Are The Two Types Of Natural Resources – A renewable resource is a resource that can be renewed naturally over time. As a result, it is sustainable despite being eaten by the human species.
Renewable resources are considered particularly important because of their ability to replace non-renewable or finite resources in energy production. In addition, renewable resources can provide cleaner energy solutions than those provided by non-renewable resources such as coal and fossil fuels.
What Are The Two Types Of Natural Resources
Renewable resources are resources that have an inexhaustible supply because they can be replenished. Solar, wind and geothermal energy are considered inexhaustible and are therefore examples of renewable sources.
Renewable Resource: Definition, Considerations, And Types
Water is also considered a renewable natural resource, as long as there is rain. Changing climate patterns have highlighted the need for conservation efforts to protect water supplies.
Other natural resources are considered renewable, although it takes time and effort to restore them. In addition, most precious metals are considered renewable because they can be reused. Since it is not destroyed during production and use, it can be recycled.
Unlike renewable resources, once non-renewable resources are used up, they cannot be replenished. As the human population continues to grow and finite resources become scarcer, the demand for renewable resources increases.
Fossil fuels have been used since the late 1880s to produce the energy we use. Renewable resources such as hydropower and wood have been used for a long time. In fact, they were the two primary sources of renewable energy until the 1990s.
Causes And Effects Of Natural Resources Misuse: Environmental Problems
In recent years, renewable energy production has increasingly come from biomass, geothermal, solar, hydro and wind energy.
Renewable sources that can replace fossil fuels for energy production are the main focus of nations around the world. Challenges to successful renewable energy production include reliability and cost.
Much research is taking place to determine the feasibility and best application of renewable energy on a large scale.
The Paris Climate Agreement is an agreement between more than 180 countries to reduce greenhouse gas emissions and limit global temperature rises to less than 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial levels by 2100. January 20 , 2021, President Joe Biden signed the United States back to the Paris Agreement after the Trump administration withdrew on November 4, 2020.

Sunlight is a widely recognized renewable resource. In fact, it has been used throughout human history to heat homes, dry and cook food, and heat water. Various technologies exist and are still being developed to collect and convert solar radiation into thermal energy that can be used for various purposes.
For example, solar photovoltaic (PV) devices or solar cells convert sunlight into electricity. Depending on the number of solar cells used, they can power small appliances or power many homes.
The challenge with using solar energy is that energy demand can vary and, at times, be unreliable. Access to sunlight depends on the time of day, prevailing weather conditions, season and geographic location.
The wind has a direct relationship with the sun. Diurnal winds occur when the sun’s heat is unevenly distributed over different parts of the Earth, including oceans and other bodies of water. The atmosphere above the earth warms the water faster than the air above it during the day when the sun is up. That warm air expands and rises. Cold air takes its place. This creates wind.

In the past, windmills were used across the United States to capture energy and extract water from wells. They still exist in some agricultural areas to provide water for livestock.
Today, wind is used to generate electricity. Wind is driven by wind turbines. The metal rotates and this drives the generator. In turn, this creates electricity.
Typically, wind turbines do not produce emissions that can pollute the air or water. Also, it does not need to be cooled with water. Although rare, they can have a negative impact on the environment if they spill oily liquids or catch fire. They can also affect life and bird species.
Hydropower is energy produced by water. It was an early source of renewable energy even before it was used to generate electricity. For example, generators turned wheels on rivers to grind grain and wood. Changes in rainfall and lack of water during droughts can affect hydropower production.

Hydroelectricity has been used to generate electricity in the United States since the 1880s. Today, most of the nation’s energy is generated at facilities located at large dams built in the 1970s.
Geothermal energy is a renewable resource that uses the heat of the earth to produce energy. Geothermal hot springs have been used for bathing for centuries. Geothermal energy was also used and is still used in district heating systems.
Geothermal energy is also used to generate electricity. Power plants for this purpose are built underground, about a mile from the surface.
Seven U.S. states have giga-megawatt power plants. In 2021, they produced approximately 16 billion kilowatt-hours (kWh) of electricity. This is about 0.4% of the total electricity production of energy companies. Those states are California, Oregon, Nevada, Idaho, Utah, New Mexico and Hawaii.

Geothermal heat pumps are another way to use heat from the ground. They transfer heat from the ground (or water) to buildings during the winter and turn it on in the summer to help with heating and cooling.
Renewable natural products that produce energy are called biomass. The process of photosynthesis uses solar energy to convert biological resources into chemical energy.
By 2021, biomass will provide nearly five quadrillion British thermal units (Btu) and about 5% of total primary energy consumption in the United States.
Renewable biomass resources include wood and wood waste, agricultural crops and waste (often used for biofuels), municipal waste including paper, cotton, food and yard waste, and animal manure and sewage.

Biofuel refers to liquid fuel and its components produced from biomass feedstock. Most biofuels are used as transportation fuel, but they can also be used for heating and electricity. These renewable resources have become more widespread in recent years as an alternative to non-renewable resources such as coal, oil and natural gas.
By 2021, the United States will produce about 17.5 billion gallons of biofuel. About 16.8 billion gallons were used. In addition, the United States was a net exporter of about 0.8 billion gallons of biofuel. The largest part of those exports was ethanol for fuel.
Although the price of biofuel is still high, some experts predict that as the price of fossil fuel rises, the price of biofuel will become more competitive.
Renewable resources are those that last despite being used or can be replenished over time even as they are used. These include solar, wind, hydro, geothermal and biomass.
Nonrenewable Resource: Definition, Features, And Examples
For example, the ability to collect and use solar energy is limited at night and when the sky is cloudy. Continuous availability of water depends on current rainfall and weather conditions.
Non-renewable resources are resources that are considered finite because of the very long time it takes nature to create them. Once used, they become unavailable. These include coal, natural gas and oil.
The advantage of non-renewable resources is that they are now readily available and the infrastructure is in place to use them to produce the energy on demand.
However, they have a negative impact on the environment compared to renewable sources. The heat trapped in carbon dioxide gas when coal and oil are burned contributes to global warming and climate change.
The Different Types Of Natural Resources You Ought To Know
Activists, consumers and government leaders are promoting renewable energy to create the energy needed without the emissions that are warming the planet and threatening life on Earth.
The spread of COVID-19 supported a decline in fossil fuel prices due to low consumption in 2020. However, when the war between Ukraine and Russia broke out in early 2022, oil prices rose sharply and remained high.
Renewable resources have become a focal point of the environmental movement, politically and economically. Energy from renewable sources puts less strain on the limited supply of fossil fuels, which are non-renewable resources.
The problem with using renewable energy on a large scale is that they are expensive, and in most cases, more research is needed to determine how best to use them.
Natural Resources Questions & Answers For Quizzes And Tests
In addition to limited supplies, energy sources such as fossil fuels damage the environment when produced and used and contribute to global warming. The first international agreement to control carbon dioxide emissions and global warming was the Kyoto Protocol, signed in 1997. More recently, world powers met in Paris in 2015 to pledge to reduce emissions and focus on rely heavily on renewable energy sources.
Incentives can encourage the use of alternative energy. For example, energy taxes impose additional costs on fossil fuels. This can make the price of renewable products competitive and attractive. As a result, people may be more inclined to use renewable energy.
Green funds, which are investment vehicles such as mutual funds, support environmentally friendly and sustainable companies by investing. This also helps to raise environmental awareness.
These incentives seem to be having an effect. According to the U.S. Energy Information Administration (EIA), in 2021 renewable energy will provide approximately 12.6 quadrillion of British thermal energy.
