Electric cars-got to be a viable option now?

[gunner]

I work in the O&G industry and have looked at countless energy saving options over decades of working on projects.

Simple payback, or simple capex vs opex trade-off has always been the screening tool. I just follow the same methodology.

Not convinced if our house was to be sold in the future solar panels would add value, and depending on the orientation, the ugliness of black panels littered on a period property roof will probably detract.

My experience is that energy saving projects rarely pass the investment hurdle and have to have a ring fenced budget accepting lower returns to be successful.

Interesting, I work in commercial real estate and my experience is quite the contrary. Solar panels and their energy savings have been shown to attract tenants, drive rents and make assets more liquid. We take into account capex, opex and valuations of course.

Obviously not going to work in every scenario.
