Are We Approaching The EV Tipping Point?

By Roy L Hales

Screen-shot-2014-03-18-at-3.43.47-PM1It has been almost ten months since the NRG eVgo Freedom Station in the Fashion Valley Mall, in San Diego, opened. It was hailed as the first station capable of supporting “all EVs on the road”. There are now eVgo networks in Los Angeles, San Francisco, the greater Washington, D.C. area, Dallas and Houston. A company spokesperson says that, in conjunction with their new partnership with BMW, they will be installing 100 DC SAE Combo Fast Chargers in California. One of their infograms shows a band of green stretching from Washington state down through California and across America to Washington DC.

We could not name the company, as our source still works there, but they use a known carcinogenic called gallium arsenide. This is not believed to be a problem as long as the panels are intact. However if they end up in a landfill the panels will be broken and the toxins can leech into the soil. Environment California recently directed me to a study that puts the toxic Issue of solar panels in context and suggests areas where the industry can improve.
