1. How to tackle air pollution
What is your proposal?
Tangent Energy's site energy storage systems automatically manages available power sources such as diesel generators, PV, wind, or the grid and stores the electricity in a battery which it dispatches in a controllable manner. The result is a typical site generator is switched off for over 60% of the week. The system also provides air pollution monitoring to report on CO2, NOx, PM, fuel and energy consumption.  
What does it do?
The system powers the site from its batteries. When the batteries are low the system automatically runs the diesel generator to recharge itself. The loads are prioritized and selectively switched on and off to achieve the most efficient load profile. All the data is visible in the web platform.
How does it meet the challenge?
The purpose of the system is to reduce emissions from burning fossil fuels. It provides users with the means to make immediate change and it presents the data showing the underlying issues which gives users evidence to support making further changes and developing a better energy strategy by using appropriately sized appliances and reducing generator sizes to appropriate levels. Reporting and comparing air pollution at every site identifies the range between best and worst cases and focusses attention to where improvements are needed. The system provides a cost-effective energy technology strategy and roadmap towards a zero-carbon future.
