Direct Current in the home

PeterRT

With more and more in the home being powered off DC (Direct Current) supplies, e.g. Battery & Solar Panels, then wouldn't it be more economical to consider extending the regulations to cover DC in the home avoiding the need for transformers?

For example, this is particularly appropriate now that lighting is dominated by LED.

       But if you start with DC then I guess you would need a rotary converter or, when the required voltage is lower than supplied voltage, I suppose you could use a woefully inefficient voltage divider. 

    Solid-state DC-DC converters are common now, and very efficient. 

     May I suggest that in UK we stick with the distribution of alternating current electricity to domestic customers.

    I don't think DC distribution in the public network is being considered at present (never say never, though, it was still present in some UK towns until 1960's I believe).

    But for some purposes, DC circuits within buildings are definitely on the increase.
