Former vice president Al Gore testified before the Congress on Friday that he supports a climate legislation which he says, will solve problems with the economy, climate and national security.

The climate bill, which he called one of the most important pieces of legislation ever introduced in the Congress, will protect the American people from skyrocketing oil prices that he says will follow once the economy recovers.

If the climate bill gets approved, it will create jobs for building solar panels, geothermal and wind farms installations. Gore also urged the Congress to include provisions in the bill in order to help people whose work may be at risk, for example, those who are employed by energy-intensive industries.

Gore - winner of a Nobel Prize for his work on global warming - testified along with former U.S. senator John Warner on the fourth day of intensive hearings at Congress.

Throughout the week, more than 50 witnesses from the energy industry, the federal government and environmental advocacy organizations gathered. The group is discussing the benefits and negative impacts of the bill which aims to reduce greenhouse gas emissions in the U.S. in order to ease global warming and gain energy independence.
