Introduction

This research report aims to provide an extensive overview of renewable energy sources. The objective is to analyze their potential, effectiveness, economic impact, and environmental benefits.

Overview of Renewable Energy Sources

Definition and Background

Renewable energy sources are derived from natural processes that are replenished constantly. This includes sunlight, wind, rain, tides, waves, and geothermal heat. Unlike fossil fuels, renewable energy sources are sustainable and have a lower environmental impact.

Types of Renewable Energy Sources

• Solar Energy: Solar energy is harnessed from the sun using photovoltaic cells or solar panels.

• Wind Energy: Wind energy is captured through wind turbines which convert kinetic energy into electrical power.

• Hydropower: Generated from the movement of water through dams or river systems to produce electricity.

• Biomass Energy: Produced from organic materials, such as plant and animal waste.

• Geothermal Energy: Obtained by harnessing heat from beneath the earth's surface.

• Ocean Energy: Includes both wave energy and tidal energy generated from oceans.

Importance and Benefits

Renewable energy sources are crucial for reducing greenhouse gas emissions and dependence on fossil fuels. They offer a sustainable and clean alternative that helps combat climate change, improve air quality, and provide energy security.

Analysis of Renewable Energy Production

Current Global Scenario

According to the International Energy Agency (IEA), renewable energy accounted for nearly 28% of global electricity generation in 2021. This marked a significant increase from previous years, driven by advancements in technology, decreased costs, and supportive government policies.
