As the impacts of climate change caused by energy use becomes more evident to world leaders, more than 1000 delegates from over 100 countries met in Bonn, Germany, to discuss the role that renewable energy will play in the future of the planet. The participants include heads of state, energy ministers, regional leaders, business, public pressure groups, business and youth groups. The 2004 International Conference for Renewable Energies, Bonn was proposed by German Chancellor Gerhand Schroeder after the World Summit for Sustainable Development in Johannesburg failed to deliver meaningful targets for the implementation of renewable energy.
