Buckminster Fuller proposed a system where energy would be the basis of a global currency and a new standard of wealth. He envisioned a "time-energy world accounting system" that tied the prices of goods and services to the resources used for their production and compensated everyone for their labor and their share of renewable energy. Fuller's ideas, dating back to the 1920s, included a "time standard" of wealth and a "true dollar" tied to the amount of energy available worldwide. He also proposed an integrated world electric grid by connecting the U.S. and Russian systems.
