California Goes for 50% Renewables by 2030

In a historic vote, California legislators have ensured that the eighth largest economy in the world is running on 50% renewable energy within just 15 years. California’s Democratic-majority legislature just acted decisively to further reduce the use of fossil energy… Read More

Novel Energy Storage Leverages Free Gravity

Gravity already supplies us with one cheap and clean form of electricity storage. We can contain and then release a weight — in this case water, with pumped hydro. When there is excess energy on the grid that no one… Read More

Hydro-Powered Irrigation: Colorado Makes Water Work

Drought has become a consistent feature of the western United States. A changing climate is leaving the area drier year-round, with natural and man-made reservoirs slowly becoming depleted. Driven by necessity, innovators in Colorado are coming up with ingenious ways… Read More
