How inspiring to meet someone equally motivated to save our Planet. Therefore, as an Ambassador I would like to introduce to you the GreenTech ideas contest ‘Imtech promotes GreenTalent’ for a more sustainable world: http://www.imtech.eu/greentalent

Take a look at the summer and winter simulations of how the CA grid might operate in 2016. Solar and wind contribute at different times of the day and, thus, reduce the need for storage. Existing natural gas is filling in when extra power is needed.

Because we have a lot of natural gas generation on line we can deal with the ‘part time’ nature of wind and solar without building storage in the short run.

As we go along battery prices will drop allowing large scale batteries to replace natural gas and we will build more pump-up storage but the lack of storage is not an issue at the moment.

1st of all, with a diverse mix of energy sources (solar, wind, geothermal, tidal, etc.) and smart grid tech, storage is not that huge of a problem. I heard some leading utility execs say essentially the same thing recently.

We can manufacture batteries.

We cannot manufacture sweet crude.

Solar and Wind Turbines face the same problem: energy storage. How to effectively store the energy during down time (cloudy/night/no-wind) would become more important going forward as solar panels and wind turbines’ prices drop. Batteries as in the current form (NiMH, Li-polymer) are in much bigger shortage than sweet crude.
