Renewable energy harnesses natural resources like solar, wind, hydro, and geothermal to generate sustainable, clean power. This vital sector addresses climate...
Renewable energy is derived from natural sources that replenish faster than they are consumed, such as sunlight, wind, rain, tides, geothermal heat, and biomass.
The primary types include solar (photovoltaic and thermal), wind, hydroelectric, geothermal, and biomass energy.
It's crucial for reducing greenhouse gas emissions, combating climate change, enhancing energy security, creating green jobs, and providing a sustainable alternative to fossil fuels.
While the operational phase of renewable energy systems typically produces no direct emissions, their manufacturing, installation, and disposal processes do have a carbon footprint, which is generally much lower than fossil fuels.
Key challenges include intermittency (e.g., wind doesn't always blow), energy storage, grid integration, and the initial investment costs for large-scale projects.
