21st century energy networks

Although this energy and transportation infrastructure served its purpose and industrialized most

20TH CENTURY ENERGY NETWORKS energy networks.

In the 20th century, electricity was generated centrally at large power-generating stations primarily
by burning fossil fuels such as coal. The electricity was then transported over long-distance The 21st century energy network — both in terms of renewable energy sources like solar, wind,
