The advantage of smaller grids is that they can potentially be isolated from the larger grid, lessoning the impact of grid outages and improving energy resiliency.Battery Storage SolutionsClean energy solutions require backup storage for when renewable resources, like the sun, are not available. Currently, the most prevalent way to do this is through lithium-ion or zinc-hybrid batteries, which can store energy for future use. For this technology to be equipped for consumers, it needs to be readily available, mass producible, and economically priced. We're seeing the same type of technology revolution with battery storage that solar technology experienced five to 10 years ago. Prices are coming down, the ability to manufacture and mass produce batteries is becoming more cost effective, and existing battery technology is being optimized. The cost-effectiveness of battery storage is especially important, since batteries typically have an expected life cycle of less than 10 years.As this technology becomes more available and affordable, it starts to make smaller community grids more feasible, enabling energy to be produced and stored locally. Incoming TechnologiesSo, what's next on the horizon for energy technology? It could likely be new applications of solar in places we previously haven't imagined. Companies and institutions are currently testing solar pavement, sidewalks, roofing, windows, and even paint. While some of these technologies are still being developed, imagine having a home made entirely out of solar products and how that would positively impact energy bills while reducing demand on the power grid.Another interesting emerging technology includes "hanging weight storage," where energy is stored by using renewable energy to physically lift a weight (like a crane) in the air. When power is needed, gravity naturally lowers the weight and the lifts act as a generator. These systems are feasible because they are simple to maintain, installation is straightforward, and they are low-maintenance. This technology is ideal for cold weather where battery storage isn't ideal, since batteries need to be kept in heated buildings.This is an exciting time to be working in energy­what was once thought of as impossible is not only becoming possible, but already being created. These clean energy solutions are good for the Earth and are also helping to build a more connected world. As battery storage solutions become more available and affordable, it starts to make smaller community grids more feasible, enabling energy to be produced and stored locally
