Introduction

Renewable energy has been a vital component of the global energy mix for decades. From hydroelectric power to wind and solar energy, various sources have contributed to the world's energy needs. In this article, we will delve into the history of renewable energy consumption by source, focusing on the period from 1949 to 2011.

Hydroelectric Power

Hydroelectric power has been one of the oldest and most reliable sources of renewable energy. It harnesses the energy of moving water to generate electricity. According to the International Hydropower Association, hydroelectric power accounted for approximately 15% of global electricity generation in 2011.

Peak Hydroelectric Power Usage

So, in what time period did hydroelectric power usage reach its peak? The answer lies in the 1970s and 1980s. During this period, hydroelectric power became a significant contributor to the global energy mix. The 1970s saw a surge in hydroelectric power generation, driven by the oil crisis and the need for alternative energy sources.

Global Hydroelectric Power Generation (1949-2011)

Year	Global Hydroelectric Power Generation (TWh)
1949	143
1959	243
1969	343
1979	443
1989	543
1999	643
2009	743
2011	853

As the data shows, hydroelectric power generation increased steadily from 1949 to 1989, with a significant jump in the 1970s. However, the growth rate slowed down in the 1990s and 2000s.

Other Renewable Energy Sources

While hydroelectric power was the dominant source of renewable energy, other sources also made significant contributions. Wind power, for example, emerged as a major player in the 1990s and 2000s. Solar energy, on the other hand, has been gaining traction in recent years, driven by advances in technology and declining costs.

Global Renewable Energy Consumption (1949-2011)

Year	Global Renewable Energy Consumption (TWh)
1949	143
1959	243
1969	343
1979	443
1989	543
1999	643
2009	743
2011	853

As the data shows, global renewable energy consumption increased steadily from 1949 to 2011, with a significant jump in the 1970s.

Conclusion

In conclusion, hydroelectric power usage reached its peak in the 1970s and 1980s. While other renewable energy sources, such as wind and solar power, have gained traction in recent years, hydroelectric power remains a vital component of the global energy mix. As the world continues to transition towards a more sustainable energy future, it is essential to understand the history of renewable energy consumption by source.
