As the world grapples with the pressing challenges of climate change, energy security, and depleting fossil fuel reserves, renewable energy has emerged as a critical solution for ensuring a sustainable future. With a growing consensus among governments, businesses, and civil societies, the global transition to renewable energy sources has gained momentum over the past decade. This blog explores the current state of renewable energy, key global developments, and how recent advancements are shaping the future of energy production.
1. What is Renewable Energy?
Renewable energy refers to energy derived from natural resources that are ‘replenished naturally’ over short periods. Unlike fossil fuels such as coal, oil, and natural gas, which take millions of years to form and contribute to carbon emissions, renewable energy sources offer ‘cleaner, more sustainable alternatives’. The major types of renewable energy include:
– Solar energy: Captured through photovoltaic (PV) cells or solar thermal systems.
– Wind energy: Harnessed using wind turbines.
– Hydropower: Energy generated by flowing water.
– Biomass energy: Derived from organic materials like plant matter and animal waste.
– Geothermal energy: Heat extracted from beneath the Earth’s surface.
– Ocean energy: Tidal and wave energy harnessed from the oceans.
2. Why is Renewable Energy Important?
The transition to renewable energy is driven by several key factors:
a. Climate Change Mitigation
Fossil fuels are responsible for the majority of greenhouse gas emissions, which contribute to global warming and climate change. Renewable energy sources produce little to no emissions, making them a critical component of strategies aimed at reducing carbon footprints and achieving net-zero emissions targets.
b. Energy Security
Many nations are heavily reliant on imported fossil fuels, making them vulnerable to geopolitical tensions and price fluctuations. Renewable energy, particularly when generated locally, reduces dependence on foreign energy sources, thereby enhancing energy security.
c. Sustainability
Fossil fuels are finite resources, and their extraction and consumption are depleting the Earth’s reserves. Renewable energy, on the other hand, is based on resources that are ‘inexhaustible’, ensuring long-term sustainability.
d. Economic Growth and Job Creation
The renewable energy sector has seen ‘massive growth’ in recent years, driving innovation and creating millions of jobs globally. The shift towards cleaner energy technologies stimulates economic activity, particularly in sectors like manufacturing, installation, and maintenance.

a. COP26 and Global Climate Commitments
The ‘26th UN Climate Change Conference of the Parties (COP26), held in Glasgow in 2021, marked a pivotal moment for renewable energy. At COP26, nearly ‘‘200 countries’ committed to limiting global warming to ‘1.5°C’ above pre-industrial levels. Achieving this goal requires a massive reduction in carbon emissions and a rapid shift towards renewable energy. Many countries pledged to phase out coal, promote clean energy technologies, and boost funding for renewable energy projects in developing nations.
Notable commitments included:
– India’s pledge to reach 50% renewable energy capacity by 2030 and achieve net-zero emissions by 2070.
– The European Union’s Green Deal, which aims to make Europe the first climate-neutral continent by 2050.
– The United States commitment to cut emissions by 50-52% below 2005 levels by 2030 and achieve 100% carbon-free electricity by 2035.
b. The Rise of Solar Power
Solar energy is rapidly becoming the cheapest and fastest-growing source of renewable energy. The cost of solar PV panels has dropped dramatically over the past decade, making solar power accessible to a wider range of countries and communities.
– ‘China’ is the world leader in solar energy, with over 250 GW of installed capacity, followed by ‘India, the ‘‘United States, and ‘‘Japan’.
– In 2023, ‘India’ set a new record by installing ‘over 12 GW of solar power capacity’ in a single year, driven by government incentives and a strong push toward clean energy.
