Renewable energy

The term renewable energy derived from sources that are naturally replenished and have a minimal environmental impact.

Unlike fossil fuels, which are finite and contribute to pollution and climate change, renewable sources are abundant and produce little to no greenhouse gas emissions or other harmful pollutants.

The use of renewable energy is a crucial component of transitioning to a more sustainable and low-carbon energy system.

Types

• solar
• wind
• hydropower,
• geothermal,
• biomass.

Benefits

• reduced greenhouse gas emissions,
• energy security,
• sustainable development: investing them promotes economic growth, creates jobs, and supports local communities while minimizing environmental impacts.
• abundant & inexhaustible: naturally replenished and virtually limitless, ensuring a long-term and sustainable energy supply.
• improves air and water quality,
• resilience and reliability,
• technological advancements.

Challenges and Considerations

• intermittency,
• infrastructure and investment,
• geographic and resource constraints,
• integration with existing systems,
• policy and regulations,
• public perception.

Leading Countries in renewable energy adaption & Policies

1. Germany:  global leader in renewable energy, particularly solar and wind power. The country’s Energiewende (Energy Transition) policy aims to phase out nuclear power and shift to a low-carbon energy system. Germany invested heavily in solar installations. Implemented feed-in tariffs to incentivize renewables, and plans to achieve 65% renewable electricity by 2030.
2. China: the world’s largest producer and consumer of renewable energy. The country made significant investments in solar, wind, hydro, and nuclear power. A major manufacturer of solar panels and wind turbines and has ambitious targets for expanding its renewable capacity.
3. United States: a leader in wind and solar energy production, with several states implementing renewable energy standards. California set a goal of achieving 100% clean energy by 2045. Offshore wind projects gaining traction along the East Coast.
4. Denmark: achieved remarkable success in wind energy, with wind power providing a significant portion of its electricity needs. The country aims to become carbon-neutral by 2050 and established a strong regulatory framework to support this development.
5. Sweden: made strides, including hydropower and bioenergy. The country set a target to become fossil fuel-free by 2040 and invested in research and development of sustainable energy technologies.
