Let's begin by exploring the global scenario of renewable energy sources. Over the last years, weβve witnessed a rapid rise in renewable energy capacity. Who can tell me some of the leading contributors to this growth?
Is it mostly solar and wind energy?
Exactly! Solar, wind, and hydropower are the main contributors. In fact, as of 2023, the total photovoltaic solar capacity exceeded 1,000 GW worldwide. Can anyone tell me which countries are at the top of this list?
I think China, the US, and Europe are among the top markets.
Right! Great job, Student_2. This trend highlights the shift towards renewable energy as a key player in the energy sector.
Why is this shift happening so quickly?
Good question! It's mainly driven by cost reductions and supportive climate policies. To remember these key contributors, think of the acronym SOW: Solar, Ocean, Wind. Anyone want to summarize what we've learned so far?
We learned that the global capacity for renewables is increasing, especially in solar, wind, and hydropower, and that major players are China, the US, and Europe.
Excellent summary, Student_4! Let's move on to discuss India's progress in renewable energy.

Now, letβs focus on the Indian scenario of renewable energy sources. As of 2022-23, India has exceeded 120 GW in installed renewable power capacity. What do you think is a significant goal for India in the upcoming years?
Is it to reach 500 GW of renewable capacity?
Yes! The Indian government has set an ambitious target to achieve 500 GW of non-fossil capacity by 2030. Why do you think this is important?
It would help reduce reliance on fossil fuels and lower emissions.
Exactly! Renewables are projected to contribute approximately 30% of India's power generation mix, moving toward 45% zero-carbon generation. Letβs think of a mnemonic to remember the key renewable sources in India: SWBS β Solar, Wind, Biomass, and Small hydro. Who can summarize our discussion?
India aims for 500 GW of renewable capacity by 2030, and renewables currently contribute about 30% of power generation.
Great recap, Student_3! This target will significantly impact India's energy landscape.

Letβs discuss the benefits of expanding renewable energy capacities. What are some benefits you think these sources provide?
They reduce dependence on fossil fuels.
Yes, reducing dependence is a primary benefit. Can anyone think of additional benefits?
They help decrease greenhouse gas emissions!
Exactly! Additionally, renewables can provide energy security and contribute to rural electrification. To help remember these benefits, think of the acronym RED: Reduce emissions, Enable security, Develop electrification. Can someone provide a summary?
Renewable energy reduces fossil fuel reliance, decreases emissions, and provides energy security and rural electrification.
Well summed up, Student_3! These advantages are crucial for sustainable development.

Chapter Content
Rapid rise in renewable capacity, driven by cost reductions and climate policies.
Solar, wind, and hydropower are the leading contributors to global installed renewable capacity.
Detailed Explanation
The global renewable energy sector has experienced significant growth in recent years. This increase is primarily due to two main factors: cost reductions in technology and the implementation of climate policies by governments around the world. As a result, renewable sources like solar, wind, and hydropower have become substantial contributors to the overall energy supply.
Examples & Analogies
Think of the renewable energy market as a car market that has started producing electric vehicles. Initially, electric cars were expensive and not widely adopted. However, as manufacturing improved and prices dropped, more consumers started buying these cars. Similarly, as solar and wind technologies have become cheaper, more countries have turned to them for clean energy.

As of 2023, photovoltaic solar capacity alone exceeds 1,000 GW worldwide, with China, the US, and Europe as top markets.
Detailed Explanation
By 2023, the total capacity of photovoltaic solar energy installations around the world has surpassed 1,000 gigawatts (GW). This means that the combined power generated by solar energy alone is now extremely significant. The leading countries in this area are China, the United States, and several European nations, which are investing heavily in solar technology to transition to cleaner energy sources.
Examples & Analogies
Consider a gigantic factory that produces a particular product. If that factory can produce 1,000 units of product consistently, it illustrates a high capacity. Similarly, the global capacity of photovoltaic solar installations indicates a major commitment to harnessing renewable energy.
