Economics is the study of how societies use scarce resources to produce valuable goods and services and distribute them among different individuals. If we think about the definitions, we find two key ideas that run through all of economics:

Sustainable energy solutions will define the 21st century.

我的座右铭是：为一点点感到满足，但希望获得更多。
