I'm amazed yet again by rooftop solar policies in your country. The unused solar energy from home panels flows back into the grid, and homeowners get credited or paid for it at retail rates. In India special both directional, installed in every participating house, accurately track this two-way energy exchange, measure what you draw from the grid and what you export.

India's Ministry of New and Renewable Energy promotes this via net metering schemes in all states, while Australia's Solar Credits and feed in tariffs make renewables viable. It's a win-win in both countries where I live, clean energy boosts and lower bills for our households! And to top it all, in Australia they lower energy charges during night time so we charge our car during night.

I always thought Holland with its large wind energy production was passing the benefit to its customers but you as always keep surprising me. Mind it, it's not a doubt on your statement but my low knowledge of the facts.
