We are quite pleased with our progress. So far we've reduced our energy consumption by nearly 2/3rd's - in two years of effort. Also in that time, we've cut our facility's water consumption by well over 90%. As we start closing in on net-zero, by recommisioning our systems, investing in more efficient devices, and increasing our on-site production, we will make sure to keep you informed of our progress. Below is our energy consumption for the past 2 1/2 years:
