Renewable Energy 101

Renewable energy is a term used to describe a group of energy technologies derived from sources that do not deplete or that can be replenished within a human lifetime. The most common renewable energy sources include:

• Solar: This technology harnesses the sun’s energy.
• Wind: Utilizes the motion of the wind to generate electricity.
• Hydropower: Generates power using moving water.
• Biomass: Refers to a broad range of technologies that utilize living or recently living organisms and waste to create energy.
• Tidal Energy: Generates electricity from the rise and fall of tides.
• Geothermal: Uses the internal heat from the Earth for energy.

It’s essential to note that while nuclear energy is often discussed in the energy conversation, it is not classified as a renewable energy source. Instead, it is considered an alternative energy source.

Although renewable energy currently accounts for a minority share of the world’s energy supply, it is the fastest-growing segment on the planet. The demand for renewable energy is rising because it offers a clean source of energy, meaning it does not directly produce greenhouse gas emissions or air pollutants.

However, despite its environmental benefits, renewable energy faces several challenges, including:

1. Low efficiencies: Some renewable sources may not be as efficient in energy production.
2. High capital costs: The initial costs for setting up renewable energy infrastructure can be considerable.
3. Intermittency: Some renewable energy sources, like solar and wind, are dependent on weather conditions, which can affect their reliability.

In summary, renewable energy is a promising path toward achieving a sustainable future, but tackling the challenges it presents will require innovation and investment.

Are you passionate about energy and its future? Student Energy is currently developing the Global Youth Energy Outlook, a youth-led report that aims to engage 50,000 young people around the world to gather their perspectives on energy! If you're between 18-30, you can participate by visiting www.bit.ly/gyeo to complete the survey. You could even win cash prizes or a fully funded trip to the International Student Energy Summit!

Student Energy is a global youth-led organization, empowering the next generation of leaders who are accelerating the transition to a sustainable, equitable energy future. With a network of 50,000 young people from over 120 countries, we are building the knowledge, skills, and networks needed to take action on energy. Discover more at www.studentenergy.org.
