What the new climate bill could mean for San Diego

The $369 billion climate package approved by the Senate on Sunday could bring San Diego a cash infusion that could move major climate projects off of wish lists and into construction — from more rooftop solar and zero-emission vehicles to electrifying buildings and port facilities.

Rep. Scott Peters, D-San Diego, said San Diego could get funding to speed the construction of electric vehicle charging networks and needed port improvements, including electric dock equipment and shore power systems that allow ships to plug in at harbor instead of idling on diesel fuel.

San Diego has moved that goalpost even closer, aiming for net zero emissions by 2035. The city passed its new Climate Action Plan last week, and this week the county will release its sweeping blueprint for cutting emissions countywide.

The federal funding could jumpstart the city’s plan to require electric power for new construction and transition existing buildings off of natural gas, said Brenda Garcia Millan, a policy analyst for the San Diego Climate Action Campaign.

She also said the bill‘s $60 billion in funding for environmental justice could help improve air quality and cut greenhouse emissions in communities most affected by air pollution, such as Barrio Logan and San Ysidro. But she cautioned that the city must have a plan in place to compete for and spend grant money for those projects.

Selecting or replacing your solar inverter(?) for your PV solar array

Inverters are an indispensable component of almost all solar electric systems. They work long hours converting the direct current (DC) electricity generated by a photovoltaic (PV) array into alternating current (AC) electricity—the type used in homes and businesses. In battery-based systems, inverters contain circuitry to perform a number of additional useful functions.

A good inverter is key to the success of a renewable energy system, so shop carefully. Size it appropriately, and be sure to consider future electrical needs. But don’t forget that you can trim electrical consumption by installing energy-efficient electronic devices and appliances. Maximizing efficiency is always cheaper than adding more capacity. When shopping for an inverter, select the features you want, and purchase the best model you can afford. Although modified square wave inverters work for most applications, you’ll likely be happier if you purchase a sine wave inverter. It’s a decision you won’t regret if you plan to operate a computer or television.
