What is renewable energy ?
Renewable energy refers to energy that is generated from sources that are naturally replenished and can be used without depleting their resources. Unlike fossil fuels, which are finite and non-renewable, renewable energy sources are sustainable and have minimal environmental impact.
There are several types of renewable energy sources:
- Solar energy: Solar power harnesses the energy from the sun through the use of photovoltaic (PV) cells or solar thermal collectors. PV cells convert sunlight directly into electricity, while solar thermal collectors use sunlight to heat water or other fluids, which can then be used for various purposes.
- Wind energy: Wind turbines convert the kinetic energy of the wind into electricity. As the wind blows, it rotates the turbine blades, which spin a generator and produce electrical power.
- Hydropower: Hydropower uses the force of moving water, such as rivers or tidal currents, to generate electricity. It typically involves building dams or barrages to capture the energy of falling or flowing water, which drives turbines connected to generators.
- Biomass: Biomass energy utilizes organic materials, such as wood, agricultural crops, and waste, to generate heat or electricity through processes like combustion or anaerobic digestion. Biomass can also be converted into biofuels, such as ethanol and biodiesel, which can replace fossil fuels in transportation.
- Geothermal energy: Geothermal power harnesses heat from within the Earth’s crust. It involves tapping into naturally occurring geothermal reservoirs, where hot water or steam is extracted to drive turbines and generate electricity.
These renewable energy sources are considered sustainable because they are continuously replenished by natural processes. They offer numerous environmental benefits, including reduced greenhouse gas emissions, improved air quality, and decreased dependence on fossil fuels.

Which country consumes 100% renewable energy?
Cutoff in September 2021, there is no country that relies completely on 100% renewable energy for its total energy consumption. However, several countries have made significant progress in increasing their share of renewable energy and have come close to meeting their energy demands with renewable sources. Here are a few notable examples:
- Iceland: Iceland is often cited as a country with a high proportion of renewable energy in its total energy mix. It utilizes its abundant geothermal and hydroelectric resources to generate a substantial portion of its electricity and heating needs. While it doesn’t exclusively rely on renewables, a significant majority of its energy comes from renewable sources.
- Costa Rica: Costa Rica has achieved impressive milestones in renewable energy. In certain years, the country has managed to generate nearly 100% of its electricity from renewable sources, primarily from hydropower, geothermal, wind, and solar. It has set ambitious goals to become carbon-neutral by 2021 and has been a global leader in renewable energy adoption.
- Uruguay: Uruguay has made substantial progress in diversifying its energy mix and increasing the share of renewables. Through significant investments in wind and solar power, the country has been able to generate a significant proportion of its electricity from renewable sources. In certain years, Uruguay has exceeded 90% renewable electricity generation.
It’s worth noting that achieving 100% renewable energy reliance for an entire country’s energy consumption is challenging due to various factors, including the intermittency of certain renewable sources, energy storage limitations, and the need for backup power during periods of low renewable generation. However, many countries are actively working towards increasing their renewable energy capacities and reducing their dependence on fossil fuels to mitigate climate change and promote sustainable development.
