This section header slide introduces the topic "What is Renewable Energy?" as section 01. It defines renewable energy as power derived from naturally replenishing sources, contrasting it with finite fossil fuels, and highlights examples like variable sources such as wind and solar, alongside controllable ones like hydro.
01
Renewable energy from natural sources that replenish, unlike finite fossil fuels; includes variable like wind and solar, controllable like hydro.
Renewable energy sources harness natural resources to generate sustainable power, as outlined in the slide. Key types include solar, which uses photovoltaic panels to capture sunlight; wind, converting turbine motion into electricity; hydro, leveraging flowing water; geothermal, drawing Earth's internal heat; and biomass, processing organic materials for energy.
The slide "Solar Power in Action" features an image illustrating photovoltaic panels that efficiently convert sunlight into electricity, often deployed in large-scale solar farms to generate renewable power in open fields. It highlights how output varies with sunlight availability, underscoring the intermittent nature of variable renewable energy (VRE), while emphasizing solar's vital role in the sustainable energy transition.

Wind farms utilize turbines to produce clean electricity, serving as a variable renewable energy (VRE) source whose output varies with wind speed and weather conditions. Due to its intermittency, advanced grid integration is essential for reliability, while offering sustainable benefits like minimal emissions and low costs.
Run-of-river hydroelectric systems harness the natural flow of rivers without large dams or reservoirs, producing variable renewable energy that fluctuates with seasonal water levels and precipitation, thus lacking consistent reliability. In contrast, dammed hydroelectric plants store water in reservoirs for controlled release, providing steady, dispatchable baseload power that enhances reliability in renewable energy portfolios compared to intermittent sources like solar and wind.

Output is variable, fluctuating with seasonal water levels and precipitation, providing renewable energy but lacking consistent reliability. | Dammed hydroelectric plants store water in reservoirs for controlled release, enabling dispatchable power. This delivers steady baseload electricity, offering reliability in renewable portfolios unlike the intermittent output of solar and wind sources. |
In 2022, renewable energy accounted for 29% of global electricity generation, with wind contributing 7.8% to the overall power mix. Solar energy saw a robust 24% yearly growth rate worldwide.

The timeline slide on the History of Renewable Energy begins with the 1887 establishment of the world's first hydroelectric power plant in Appleton, Wisconsin, followed by 1950s post-WWII advancements in modern wind turbine technology. It continues with the 1970s solar photovoltaic boom triggered by the 1973 oil crisis, culminating in the 2020s where solar and wind dominate new global power capacity additions, surpassing fossil fuels in many regions.
1887: First Hydroelectric Power Plant The world's first hydroelectric plant is built in Appleton, Wisconsin, marking the start of renewable energy generation. 1950s: Advancements in Wind Turbine Technology Post-WWII innovations lead to modern wind turbines, boosting wind power as a viable renewable source. 1970s: Solar Technology Boom After Oil Crisis The 1973 oil crisis spurs rapid development in solar photovoltaic cells and panels worldwide. 2020s: Variable Renewables Dominate New Capacity Solar and wind lead global additions to power capacity, surpassing fossil fuels in many regions.
The slide's conclusion emphasizes that renewables provide clean, infinite energy sources, though they demand innovation to integrate variable renewable energy effectively. It urges an immediate transition for a greener planet and calls for support of policies to join the renewable revolution and build a sustainable future.
Renewables offer clean, infinite energy but require innovation for VRE integration. Transition now for a greener planet!
Join the renewable revolution! Support policies for a sustainable future.
