Dave Renne, President, International Solar Energy Society (ISES)
For many years, renewable energy systems were seen as dependent on non-renewable sources. Challenges of cost, variability, storage and ancillary services have been put forward as barriers to a renewable future. However, an increasing number of cases describe 100% renewable energy systems, utilizing the differentiated, but mutually supportive, characteristics of different renewable sources. Leading energy agencies will present the current status of the renewables sector, and representatives of each renewable energy technology will contribute on behalf of their constituencies.

Solar Opportunities
• Distributed and modular technologies: provide
electricity, heating and cooling, and building efficiency
services
• PV growth driven by technology efficiency and
performance improving
• Costs are dropping - grid parity achievable
• Variability issues addressed by geographic diversity;
solar forecasting; energy storage (e.g. hydro)
• Solar can augment hydro resources and contribute to
overall system supply.
