Which of these is a factor in the U.S. need to find alternative energy sources?

A. Worries about overdependence on nuclear power
B. Political instability abroad
c. The problems of the car industry
D. Problems with interstate commerce

ANSWER:  B. Political instability abroad

The US was searching for alternative sources as the original sources that were being used were not going to last forever

The fossil fuels are the main source of energy in the USA, but they are also the main source of pollution, mostly atmospheric pollution. Through the burning of the fossil fuels enormous amounts of CO2 are released into the atmosphere. That is causing pollution of the atmosphere, as well as changes in the climate, making the climate more unpredictable, and also changing certain areas from suitable for agriculture to not suitable for it. That has led to lot of warnings and concerns about the usage of the fossil fuels, so there’s numerous attempts and researches into the field of alternative energy sources, especially into the usage of the renewable energy sources in order to protect the environment, and with it protect ourselves as well.

What Is Alternative Energy? 

Fossil fuels (oil, coal, and natural gas) are our most traditional source for power generation. Therefore, the energy that’s produced from any source other than fossil fuels is alternative energy. In other words, alternative energy is any amount of energy derived from non-fossil fuel sources. Generally speaking, using alternative energy has a low environmental impact.

What’s the Difference Between Renewable and Alternative Energy Sources? 

We now know that alternative energy sources are any source we use to supplement or even replace traditional energy sources used for power generation. You could almost say the same thing about renewable energy sources. But there is one subtle difference between the two. All renewable energy sources fall under the category of alternative energy sources, but it doesn’t work the other way around.  

That’s because renewable energy sources are derived from naturally replenished sources or processes of Earth, such as the sun, wind, and water. We refer to these resources as renewable or sustainable (as in sustainable energy) since, unlike fossil fuels, this naturally occurring continual renewal makes them inexhaustible. However, it’s possible for there to be alternative energy sources that are exhaustible, and therefore not renewable. That’s the difference. So what alternative energy source is exhaustible? You’ll have to continue reading to find out. 

What Are the Best Types of Alternative Energy Sources? 

The equipment necessary to harness energy from alternative sources used to be so expensive that it wasn’t practical for consumer use. However, thanks to increased demand, more experienced energy developers, competitive supply chains, improved renewable technologies, and enhanced energy efficiency capabilities, that’s no longer the case.  

In fact, the International Renewable Energy Agency (IRENA) released a report back in 2020 showing how renewable power has now become increasingly cheaper than fossil fuels for electricity generation. Let’s look at a few of the best alternative energy sources we use today. 

What Is the Most Efficient Alternative Energy Source? 

When it comes to energy efficiency, the leader of the renewable energy pack is wind energy. Behind wind comes geothermal energy, hydropower, nuclear energy, and then solar power.

What Are the Most Reliable Sources of Energy? 

Out of all the known energy sources, nuclear energy has the highest capacity factor by far. Nuclear power plants are able to produce maximum power over 93% of the time on an annual basis. Next in line comes geothermal, followed by natural gas.

Natural gas is considered the cleanest burning and most reliable fossil fuel, but it still isn’t a clean energy resource. However, there is an alternative called renewable natural gas (RNG). RNG also goes by the name of biomethane and is produced from livestock, landfill waste, and other organic materials through anaerobic digestion. While it’s not a fossil fuel, RNG is completely identical to conventional natural gas in chemical make-up, allowing them to use the same distribution system.   

Most of our energy is nonrenewable

In the United States and many other countries, most energy sources for doing work are nonrenewable energy sources:

  • Petroleum
  • Hydrocarbon gas liquids
  • Natural gas
  • Coal
  • Nuclear energy

 

These energy sources are called nonrenewable because their supplies are limited to the amounts that we can mine or extract from the earth. Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and animals that lived millions of years ago. That is why we also call those energy sources fossil fuels.

Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal.

Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity. Scientists think uranium was created billions of years ago when stars formed. Uranium is found throughout the earth’s crust, but most of it is too difficult or too expensive to mine and process into fuel for nuclear power plants.

There are five major renewable energy sources

The major types or sources of renewable energy are:

  • Solar energy from the sun
  • Geothermal energy from heat inside the earth
  • Wind energy
  • Biomass from plants
  • Hydropower from flowing water

They are called renewable energy sources because they are naturally replenished. Day after day, the sun shines, plants grow, wind blows, and rivers flow.

Renewable energy was the main energy source for most of human history

Throughout most of human history, biomass from plants was the main energy source, which was burned for heat and to feed animals used for transportation and plowing. Nonrenewable sources began replacing most of renewable energy use in the United States in the early 1800s, and by the early-1900s, fossil fuels were the main sources of energy. Use of biomass for heating homes remained a source of energy but mainly in rural areas and for supplemental heat in urban areas. In the mid-1980s, use of biomass and other forms of renewable energy began increasing largely because of incentives for their use, especially for electricity generation. Many countries are working to increase renewable energy use as a way to help reduce and avoid carbon dioxide emissions.
