The MP for Totnes is calling for it to be cheaper and easier to charge electric cars.
Dr Sarah Wollaston wants to see communal charging infrastructure in towns and rural areas.
The MP told Parliament: "One of my constituents is keen to invest in solar and Tesla-style wall plugs so that they can recharge vehicles and so on, but the cost of installing the necessary three-phase electricity supply is a problem.
"Does she feel that that would be a better area for the Government to invest in and allow us to expand renewables?"
In response Rachel Reeves Chair, Business, Energy and Industrial Strategy Committee, said: "Electric vehicles have been discussed quite a bit already today, and much more could be done to encourage people to buy them and to make it easier for people to charge them, as well as to get the charging infrastructure in all communities, including more rural ones.
"Our Committee has produced several reports over the last few years on practical things that the Government could do.
"It has been disappointing at times that our recommendations and suggestions are often rejected by Ministers, when if they had accepted them, we might be a little closer to meeting some of our objectives.
"On electric vehicles, our Committee recommended that the target of 2040 be brought forward to 2032, and that was before the Government committed to net zero."
