The Oil Drum | The Alternative Energy Matrixtheoildrum.com/node/8925The Matrix. Would you like to know what the matrix is? Okay. I'll tell you—in a bit. For each of the major energy hopefuls I have discussed on Do the Math, I characterize their various attributes in a three-tier classification: adequate (green); marginal (yellow); or insufficient (red)—possibly a showstopper.The scheme is qualitative, and I am sure some will disagree with my assignments.
Zhangbei VSC-HVDC Power Transmission Project, China project is intended to ensure sufficient reliable, low-carbon power supply for the 2022 Winter Olympics to be held in Beijing. The Zhangbei VSC-HVDC power transmission system will be capable of transmitting approximately 14.1 terawatt-hours (TWh) of clean energy to Beijing while offsetting 12.8 million tonnes of carbon dioxide emission annually.
