🌞 Solar Energy: Transforming the World of Power

What is Solar Energy?

Solar energy harnesses sunlight using photovoltaic (PV) panels or solar thermal systems. PV panels convert sunlight directly into electricity and have become one of the fastest-growing renewable technologies globally -power-energy-growth-record-us-climate-china?utm_source=chatgpt.com" rel="noopener" target="_blank">vox.com-energy?utm_source=chatgpt.com" rel="noopener" target="_blank">irena.org.

Rapid Expansion and Global Capacity

Solar PV is experiencing exponential growth. Installed capacity surged from roughly 710 GW in 2020 to about 1 865 GW by the end of 2024, with 451 GW added in 2024 alone—accounting for over 75% of all new renewable capacity -energy?utm_source=chatgpt.com" rel="noopener" target="_blank">irena.org.

Why Solar is So Affordable

The cost of solar PV has been steadily declining, with levelized cost of electricity (LCOE) almost halving from $0.16/kWh in 2014 to $0.044/kWh by 2023—making it about 56% cheaper than new fossil fuel power atOptions = { 'key' : '9435e8cf6a75c73d33e34afd166cf41c', 'format' : 'iframe', 'height' : 90, 'width' : 728, 'params' : {} }; -energy?utm_source=chatgpt.com" rel="noopener" target="_blank">irena.org. As PV installations double, prices naturally drop by nearly 25% each time .
