Renewable Energy in Lebanon - Because of frequent and lengthy power outages, many families and businesses in Lebanon make use of diesel generators, which pollute the environment. Wind turbines and photovoltaic systems are promising alternatives. A project initiated by the UN links up decentralized renewable energy sources to the grid. A net-metering system keeps track of how much green energy each small provider feeds into the grid. That earns the provider credits for energy to be taken from the grid at a later date.

The prevailing view is that child labor must be abolished, but child workers in Bolivia -- and elsewhere -- argue there is no alternative for now, and are fighting for their rights. Child workers in Bolivia have set up their own labor union. They are demanding decent pay, working hours that do not conflict with the school day, and better conditions. They say they have to work to feed themselves and their families. In their eyes, child labor should only be banned when adults succeed in making enough to support their families.
