The graph shows the percentage of households in a European country using different types of renewable energy (solar, wind, and biomass) for heating and electricity between 2000 and 2020.
In 2000, only 10% of households used wind-generated energy, and that number steadily rose over the past 20 years, standing at 30% in 2020, three times higher than two decades ago.
In contrast, biomass was not nearly as successful. Starting at 15%, its usage fluctuated between fifteen and twenty percent, peaking in 2012, showing no meaningful trend, neither positive nor negative one.
The most successful of them all was solar energy, which was used by only 5% of households in 2000 and rapidly rose, arriving at 25% today, exactly five times higher than its starting point.
Overall, we can see that both solar and wind energy have become increasingly more popular over the past 20 years, with that increase showing no signs of slowing down. On the other hand, we have biomass, which while being the most used renewable energy source in 2000, failed to catch up to modern times and is likely to continue stagnating until it becomes more practical.
