Achieving 100% output from an energy source refers to a scenario where the generation capacity of that source is fully utilized, producing electricity at its maximum potential. This can occur under optimal conditions, such as favorable weather, peak demand periods, or advancements in technology that enhance efficiency.

### 🌞 Solar Power: Harnessing the Sun's Full Potential
In the United Kingdom, a record-breaking spring in 2025 saw solar energy account for over 10% of the country's electricity generation in both March and April. This surge was attributed to a combination of sunny weather and an increase in solar capacity, now at 18.2 gigawatts, with 1.5 million homes equipped with solar panels. The UK's government aims to triple solar capacity by 2030, aiming for a future where solar power consistently operates at or near 100% output during daylight hours. ([thetimes.co.uk][1])

### 🌬️ Wind Power: Tapping into Atmospheric Energy
Wind energy has become a significant contributor to global electricity generation. In 2024, wind supplied over 2,494 terawatt-hours of electricity, accounting for 8.1% of world electricity. With about 100 gigawatts added during 2021, global installed wind power capacity exceeded 800 gigawatts. Countries like Germany have regions where wind energy production meets or exceeds local electricity demand, especially during peak wind conditions. ([en.wikipedia.org][2])

### 🌊 Hydropower: Consistent and Reliable Generation
Hydropower remains one of the most reliable renewable energy sources. For instance, in Costa Rica, hydroelectric power accounts for approximately 80% of the country's electricity generation. During periods of high rainfall, hydropower plants can operate at full capacity, ensuring a stable and continuous supply of electricity. 
Geothermal energy provides a consistent and sustainable source of power. Countries like Iceland and Costa Rica utilize geothermal energy extensively. In Costa Rica, geothermal power contributes around 12.9% to the national electricity supply. The Miravalles Geothermal Power Plant, located on one of the country's active volcanoes, exemplifies the effective use of geothermal resources to meet energy demands.
