Types of renewable energy resources include moving water (hydro power, tidal and wave power), thermal gradients in ocean water, biomass, geothermal energy, solar energy, and wind energy.
What is the best alternative to coal?
According to the National Aeronautics and Space Administration (NASA), nuclear power is the most effective substitute to challenge fossil fuels for future energy consumption. Compared to coal, gas, oil, and ethanol, nuclear power produces almost negligible adverse climate effects.
What renewable resource can replace coal?
While some previous studies have emphasized the high cost of carbon taxes or caps, the new study shows that replacing coal with more gas generation, as well as renewable sources like wind, solar and geothermal energy, would result in only a moderate increase to consumers in the cost of electric power – at most, 20%.
What products can be made with coal?
The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses.
What can we use other than fossil fuels?
What Could We Use Instead of Fossil Fuels?
- Wind. Massive wind turbine farms have already been installed all over the world, providing the world with its most popular renewable energy option.
- Solar. This is a form of renewable energy that has been used for ages but is only now becoming popular. …
- Biofuels. …
- Hydrogen. …
- Nuclear Power.
How much does coal contribute to global warming?
Coal is the single biggest contributor to anthropogenic climate change. The burning of coal is responsible for 46% of carbon dioxide emissions worldwide and accounts for 72% of total greenhouse gas (GHG) emissions from the electricity sector.
Is coal the cheapest source of energy?
Of all the fossil-fuel sources, coal is the least expensive for its energy content and is a major factor in the cost of electricity in the United States.

Will natural gas run out?
When will we run out of coal and natural gas? Coal and natural gas are expected to last a little longer. If we continue to use these fossil fuels at the current rate without finding additional reserves, it is expected that coal and natural gas will last until 2060.
Can we eliminate fossil fuels?
It is not feasible to immediately stop extracting and using fossil fuels. The global economy, human health and livelihoods currently depend heavily on oil, coal and gas. But over time, we need to displace fossil fuels with low-carbon renewable energy sources.
What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite.
Is Coal still being formed?
The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.
What are the disadvantages of coal?
The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
What is the best form of alternative energy?
The top 5 commercial renewable energy sources, as ranked by market share and growth, are:
- Emerging & Emissions Boosters.
What are examples of alternative fuels?
Alternative fuels are transportation fuels that are not derived from petroleum, and they include ethanol, electricity (used in plug-in electric vehicles [PEVs] such as plug-in hybrid electric vehicles [PHEVs] or battery electric vehicles [BEVs]), hydrogen, compressed or liquid natural gas, and gasoline and diesel …
