Introduction
Social development depends entirely on energy because it enables the operation of industrial sectors together with transport systems and houses and enables technological advancements. The main sources of energy during human history have been fossil fuel materials including coal oil natural gas alongside additional resources.
Energy sources from fossil fuels resulted in destructive environmental consequences as well as global warming and the depleting of resources. The process of fossil fuel combustion generates carbon dioxide (CO₂) together with other dangerous emissions that both trigger climate change and decrease air quality. Due to their limited nature fossil fuel reserves create sustainability problems for the future.
The utilization of renewable energy provides clean sustainable solutions to replace the traditional fossil fuel power systems. The renewable energy sources naturally regenerate themselves with no depletion during time periods.
The production of renewable energy remains stable over time because these sources do not share the same weather vulnerabilities that affect fossil fuel energy. Several nations are spending large sums on renewable energy installation to handle higher energy requirements while fighting environmental deterioration.
The analysis investigates various forms of renewable power sources as well as their strengths and weaknesses regarding their impact on future global energy sector operations.

The main focus should be on understanding the economic effects of biomass energy resources. By using biomass energy people gain jobs and rural areas become stronger and the nation becomes less reliant on fossil fuels which makes it an essential component of sustainable economic development.
Advantages:
Biomass energy achieves carbon balance because plants take in atmospheric CO₂ during their development period which counters the release of emissions when the biomass burns.
The recycling method of agricultural waste together with municipal waste becomes possible through this practice.
The power output from biomass remains stable throughout time which makes it different from solar and wind energy.
Challenges:
When humans maintain biomass systems at an unsustainable rate forests become at risk of destruction.
An improper management approach to biomass burning leads to pollutant emissions.
The demand for crop-based biofuels as alternative fuel sources conflicts with food production which drives up food market costs.
Geothermal Energy
The underground heat from the planet operates geothermal energy to produce power and at the same time provides heat energy for residential buildings and commercial and industrial facilities. People can access the renewable energy source by extracting heat from beneath the ground where hot water and steam exist as reservoirs for both power generation and heating needs. Public interest focuses on whether geothermal power adoption would be feasible in Georgia. Direct-use applications and power generation facilities can operate in specific Georgian locations because of the region’s geothermal resources allowing Georgia to boost its renewable energy production while decreasing its fossil fuel dependence.
Advantages:
Power plants using geothermal energy deliver dependable energy flow at all times.
The environmental consequences from geothermal plants are significantly lower than those from fossil fuel-based plants.
Geothermal energy needs fewer lands to operate in comparison to solar and wind power plants.
