The installation of solar panels to electrify 1 million houses in Bangladesh is in my opinion great news, not just for the KWh produced for those people by clean means reducing some CO2 tons.
It also means that for poor people off-grid solar energy makes more sense than whole big investment in new grid systems fed by fossil fuels with uncertain costs in the future.
Al also means that the technology developed in rich countries (and not so rich ones) after a fossil fuel based 200 year industrialisation maybe effectively used to start using low-carbon electricity in places that have not known it before.
Symbolically means that it is possible to start improving every day life conditions based on solar energy of small-scale without going the fossil way from the beginning, becoming rich and after that reducing emissions.
And finally, it means that for many people living with almost nothing in many places, they can dream of improving their living standards without spoiling the climate of their grandchildren.
