G08: Sciences Physics - Energy: Geothermal & biomass

Geothermal energy is heat that comes from inside Earth. It is an alternative energy source that can be used for cooking, bathing, and heating.

Geothermal energy, form of energy conversion in which heat energy from within Earth is captured and harnessed for cooking, bathing, space heating, electrical power generation, and other uses.

These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly.

Geothermal energy is a green and renewable alternative form of energy harvesting. It is heat produced deep within the earth that can be transformed into both heat and electricity.

Global geothermal power generation capacity stood at 15,608 MW at the year-end 2020. The current pandemic situation clearly slowed down development with limited growth reported. Turkey represents nearly all geothermal generation capacity added in 2020.

There are geothermal power plants all over the world, but a group of ten stand out as seriously powerful producers. Read on to learn of the largest geothermal energy plants on Earth.

People have used biomass energy—energy from living things—since the earliest “cave men” first made wood fires for cooking or keeping warm. Today, biomass is used to fuel electric generators and other machinery.

Biomass consists of all of the biological material in a community, including living organisms, or parts of living organisms, as well as waste products and incompletely decomposed remains of living organisms. The term broadly includes plants (referred to as phytomass), bacteria, fungi, and animal material, or zoomass.

The existing challenges of biomass supply chain related to different feedstock can be broadly classified into operational, economic, social and policy and regulatory challenges.
