Study Notes

Energy Sources and Types: Focus on Renewable Energy

Energy sources can be broadly categorized into two groups: renewable and non-renewable. Renewable energy sources derive power from naturally recurring resources, offering a cleaner and more sustainable alternative to traditional energy sources. Some of the most common renewable energy sources include:

Solar Energy: This energy harnesses the sun's radiation to generate electricity or thermal energy directly through devices known as photovoltaic panels or indirectly via technologies like concentrating solar power (CSP).
Wind Energy: Harnessed from the movement of air, wind turbines convert wind's kinetic energy into electrical power.
Geothermal Energy: Derived from the Earth's internal heat, it involves harnessing steam or hot water from deep underground and using it to generate electricity or direct heat.
Hydropower: Utilizes the force of moving water to generate electricity, often through dams or run-of-the-river structures.
Biomass Energy: Produced from organic matter, typically from plants and animal waste, through combustion or gasification to generate heat, electricity, or biofuels.

While renewable energy sources offer environmental benefits, their implementation faces challenges such as varying levels of energy output, high upfront costs, and the need for energy storage solutions. Despite these obstacles, there is growing interest in transitioning to cleaner energy sources as businesses seek to reduce their carbon footprints.
