news article link

A new bill has been unanimously passed by the House of Representatives, the Senate, and President Obama to electrify Sub-Saharan Africa.  Currently, about 30% of Sub-Sahran Africa's population has access to electricity.  This bill is going to give 20,000 megawatts of energy by 2020 and create greener energy along with this project.  In order to electrify the Sub-Saharan area there is going to be a system of loan guarantees. For the creating greener energy project,  the US Inport-Export Bank is going to give about $7 billion.  With gaining more electricity, citizens of the Sub-Saharan area have safer and easier access to education, businesses can stay open when it is dark out, create more job opportunities, promote greener energy and economic growth.
