This is incredibly wasteful and will end up being a net-negative for greenhouse gas emissions by crowding out other, more efficient uses of that electricity besides heating things up. One of the first things they teach you in engineering thermodynamics is that electricity is very high quality energy compared to process heat, and that you can do a lot more useful things with electricity such as powering motors or electronics. Electricity generation typically results in lots of waste heat, which you would be far better off recycling into process heat through cogeneration instead of what this article is doing, which is throwing away process heat to convert electricity into even more process heat.

Typically, but may no longer be true with renewables. I don't think any of solar pv, wind, and hydro generates significant heat in the process of their power generation.
