A New Hampshire in-home energy storage program saved money and helped the grid

Solar power is an important renewable energy in Germany, but when the sun is out, it can overpower the grid. Likewise, when the sun is not out, the reception of solar power decreases. Germany has piloted battery installations that store solar energy for use when the sunlight is not plentiful and has successfully incentivized citizens to use them to lower costs.

Localized, distributed energy systems are popping up around California. As the larger electricity system becomes less reliable in the face of wildfires, more individuals are turning to microgrids and solar energy with help from organizations like Clean Coalition and Stone Edge Farm Microgrid. While still happening on a small scale, such energy systems may become more popular as its sustainability in a changing climate shows to be more resilient.

Sage Geosystems has developed a geopressured geothermal battery system in Texas that uses oil-drilling techniques to store energy underground for 4-6 hours—longer than lithium-ion batteries. This is one stage in a plan to replace an aging coal plant with renewable energy, though the system is not yet operational or connected to the grid.

In an effort to reduce greenhouse gas emissions, the United States’ Inflation Reduction Act uses tax credits to encourage the adaptation of and investment in renewable energy across the country.

Years after the California Energy Commission funded and launched demonstration microgrids, they’re seeing results. These microgrids, which are localized energy sources that can work independently from large electric grids, were fairly costly, but have shown demonstrable success in lowering utility bills and delivering low-carbon power. As the Commission moves forward with this effort, they hope to continue to learn by doing and improving their processes.

As the global demand for energy continually increases, the strain on natural resources and the detrimental effects of fossil fuels become more problematic. But new developments in renewable energy technologies may provide new solutions. Minesto, a company based out of Northern Ireland, has a new device - structured something like an underwater kite - that allows for the constant harvesting of tidal power, regardless of current weather or wave conditions.

Vehicle-to-grid (V2G) technology allows electric vehicles to send stored battery power back to utilities during peak demand periods. Early pilot programs in Maryland and California have demonstrated reduced grid stress, lower electricity costs, and the potential to transform millions of parked EVs into a distributed energy storage network.

By integrating data centers with district heating systems, Nordic countries are successfully reusing waste heat to warm thousands of homes, significantly reducing energy costs and emissions while highlighting geographic, regulatory, and power consumption challenges to scaling the approach further.

Utility companies across the United States are using virtual power plants to meet electricity demand, access backup power, and lower the electric bills of participants. To make these power plants work, the utilities use energy from the battery storage systems of customers who have home solar arrays.

New York City’s new curbside composting program collects food waste from residents in Queens to divert it from landfills. Microorganisms break down the food scraps in a process called anaerobic digestion that creates biogas used to heat 2,500 homes.
