What is meant by the term renewable and why is it important? (2023)

What is renewable energy and why it's so important?

Renewable energy is a source of power that comes from clean and natural resources. This means that it does not harm the environment around it, nor will it ever run dry. It contains no nasty chemicals or toxic ingredients — it simply generates power. In other words, it does all the hard work for us.

Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security and lower risk of fuel spills while reducing the need for imported fuels. Renewable energy also helps conserve the nation's natural resources.

Definition of renewable

1 : capable of being renewed renewable contracts. 2 : capable of being replaced by natural ecological cycles or sound management practices renewable resources.

Cheap electricity from renewable sources could provide 65 percent of the world's total electricity supply by 2030. It could decarbonize 90 percent of the power sector by 2050, massively cutting carbon emissions and helping to mitigate climate change.

Non-renewable resources deplete over time. Renewable resources include sunlight, water, wind and also geothermal sources such as hot springs and fumaroles. Non-renewable resources includes fossil fuels such as coal and petroleum. Most renewable resources have low carbon emissions and low carbon footprint.

Renewable energy sources like wind energy, solar energy, and hydropower are sustainable forms of energy because they have a low environmental impact, are widely available, and are naturally replenished.

Renewable resources include solar energy, wind, falling water, the heat of the earth (geothermal), plant materials (biomass), waves, ocean currents, temperature differences in the oceans and the energy of the tides.

Renewable sources of energy can help countries mitigate climate change, build resilience to volatile prices, and lower energy costs. This is especially critical now as spiking fossil fuel costs, triggered by the war in Ukraine, are debilitating poor energy importing countries.

renewable resource. A resource that is replaced as it is used. Resources such as wood, wind, water or solar energy, that can or will be replenished quickly.

Adjective. Able to be renewed; capable of renewal. (of a resource) Sustainable; able to be regrown or renewed; having an ongoing or continuous source of supply; not finite.

What is the base word of renewable?

renewable (adj.)

"capable of being renewed," 1727, of a lease, etc., from renew (v.) + -able.

Renewable energy is energy that has been derived from earth's natural resources that are not finite or exhaustible, such as wind and sunlight. Renewable energy is an alternative to the traditional energy that relies on fossil fuels, and it tends to be much less harmful to the environment.

Wind comes out on top by a wide margin over all the other sources. It is followed in order by geothermal, hydro, nuclear and solar.

The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. This means that nonrenewable resources are limited in supply and cannot be used sustainably.

Resources are characterized as renewable or nonrenewable; a renewable resource can replenish itself at the rate it is used, while a nonrenewable resource has a limited supply. Renewable resources include timber, wind, and solar while nonrenewable resources include coal and natural gas.

In any discussion about climate change, renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures. That's because renewable energy sources such as solar and wind don't emit carbon dioxide and other greenhouse gases that contribute to global warming.

When it comes to energy efficiency, renewable energy is generally more efficient than non-renewable energy. The energy we get from wind, the sun, and hydro turbines can be reused without relying on an exhaustible or finite element.

Renewable energy is reliable because it is both unlimited and domestic. Between the four primary modes of renewable energy generation in the U.S., wind, solar, biomass, and hydro, there is the potential to generate 100% of the electricity needed to meet the energy demands of the entire country.

What energy is renewable?

Renewable energy is energy that comes from a source that won't run out. They are natural and self-replenishing, and usually have a low- or zero-carbon footprint. Examples of renewable energy sources include wind power, solar power, bioenergy (organic matter burned as a fuel) and hydroelectric, including tidal energy.

However, the barriers (social, economic, technological and regulatory) existing in this sector prevents the development and penetration of renewable energy globally.

Renewable energy resources need priority because: 1) the overwhelming scientific evidence that anthropological emissions of greenhouse gases from carbon combustion threaten catastrophic results from rapid climate change; 2) the severe health and environmental consequences from fossil fuel combustion being experienced ...

Why is using renewable energy sources significant? It contributes to the sustainability of natural resources.
