Renewable refers to a resource or form of energy that can be replenished over time by natural processes, as opposed to being finite. This concept is central to the development and use of renewable energy sources, which aim to reduce reliance on fossil fuels and mitigate the effects of climate change.

Energy types classified as renewable include:

Solar energy, generated from sunlight and often used to power homes, industries, or transportation systems via photovoltaic cells or solar panels.

Wind energy, harnessed using wind turbines that convert kinetic energy into electrical power.

Hydro energy, derived from the movement of water in rivers, oceans, or tidal currents, typically used to generate electricity.

Geothermal energy, sourced from the heat within the Earth's core, frequently used to produce electricity or provide heating and cooling.

Biomass energy, produced from the organic matter of plants and animals, such as wood, agricultural waste, or wastewater, often used to generate heat or electricity.

Advantages of renewable energy include lower operational costs, reduced greenhouse gas emissions, and improved energy security, as resources are not as susceptible to price fluctuations or geopolitical tensions as fossil fuels. However, high initial investment costs, land use requirements, and infrastructure challenges can make the implementation of renewable energy sources unviable in certain settings.

Efforts to increase the share of renewable energy in global energy production have been ongoing, with some countries setting ambitious targets to transition away from fossil fuels and toward low-carbon economies. As technology advances and the costs associated with renewable energy continue to decrease, its role in meeting the world's energy needs is likely to expand.
