Sustainable energy in far away places
Bringing electricity to remote areas is expensive On 16th December 1935, the Pickwick Electric Cooperative was set up to bring electricity to a poor and heretofore backward part of the US state of Tennessee. A local farmer, when invited to speak a ...
Can a very large power system be operated with only distributed solar generation?
Last week I delivered training to TenneT TSO staff and we discussed, amongst others, the consequences of the growth of the variable renewable share. The following question came up: “Is it possible to run a large (size of Europe or US) electric powe ...
Solar and Snow: Unlikely allies on the energy landscape?
Prior to 2008, predicting photovoltaic (PV) system energy loss due to snow was a rare topic. The most significant markets for PV were in understandably sunny and warm climates, and no analytical models were available in the literature t ...
