Via Yale 360, the need for solar power summed up in the world's smallest nutshell:
"The poorest fifth of the world pays one-fifth of the world’s lighting bill — but receives only .1 percent of the lighting benefits...The money is on the table. It’s just on the wrong plates. Purchase and finance of solar power for 1.2 billion people would cost about $10 billion a year over a decade. The 11 countries with the largest number of households without electricity spent $80 billion each year subsidizing fossil fuel — only 17 percent of which benefits the poor."
