World’s First Ever Water-Free Laundry

In the midst of a drought, wouldn’t a water-free laundry be nice?

Well, it’s here. With a grant from the Energy Commission, CO2Nexus is wrapping up an experimental project to bring a water-free laundry machine to market. Aramark, a respected Fortune 500 company, is demonstrating the technology in Los Angeles and piloting a process that doesn’t use a drop of water and can cut operational costs by 50 percent.

The process uses carbon dioxide as a textile cleaner. Carbon dioxide is a naturally occurring and abundant gas that has excellent cleaning properties when converted to a liquid. When the carbon dioxide is returned to a gas, the fabric is clean and dry with minimal recyclable waste. Traditional dry cleaning is a similar process, but uses a petroleum or synthetic solvent and produces some emissions.

Results at the Aramark laundry, where the carbon dioxide process was used for “clean room” garments, found the process is gentler on fabric than a traditional wash-dry cycle, extending the life of clothing resulting in less shrinkage and wear.

While the process is designed for specialty garments, at one laundry, it is estimated the annual water savings would be 60 million gallons. That’s equal to the amount of water 850 homes would use in a year.

The process also uses less energy, cutting utility costs by nearly half.

New Solar Array Along the American River

On a slash of land along the American River just a stone’s throw from downtown Sacramento, the result of a California Energy Commission grant is sparkling in the sunlight.

It’s a solar array that will produce up to 1.5 megawatts of electricity that can be exported to the state’s grid. That is enough energy to power more than 400 average-size homes. The project makes use of land that once was part of an old landfill. The acreage has limited use because there is methane gas trapped below the surface that should not be disturbed.


Enter a field of solar panels, facing south, that will make use of the fastest growing sector of renewable energy. The project is under construction and expected to be completed later this summer. It is being developed by Conergy and will provide power to the Sacramento Municipal Utility District (SMUD).


California is the largest producer of solar power in the nation. It also ranks first in the nation for the number of solar jobs -- 47,223 in 2013 – according to the Solar Foundation.

Keep Buildings Airtight

Picture this: you have your house insulated but are still too cold in the winter, too hot in the summer, and your energy bills are racking up.

Sound familiar? This problem is usually caused by small, open areas in a building exterior where warm or cool air from the inside escapes or exterior air sneaks in. Using the air conditioner or heater to compensate for it being too hot or cold due to the gaps can drive up energy bills.

The California Energy Commission awarded a grant to the Western Cooling Efficiency Center at UC Davis to research methods and technologies to save energy. As a result, the center developed an aerosolized sealant spray that detects and seals areas where air leaks, which could help reduce up to 30 percent of the energy needed to heat and cool a home or office.

Aerosolized sealant spray used during construction
The potential for this product is dramatic. If all commercial and residential buildings used aerosolized sealing, monthly savings could exceed $1.5 billion per year. In addition, the sealant spray can lower construction costs. Instead of taking eight hours, contractors can seal a 1,200 square foot home in half that time.

A Window Even Smarter Than Your Phone?

Have you ever been in a room where the light and heat coming through the window made you uncomfortable? There’s a cool clean technology that is designed to fix that.

Milpitas-based View Incorporated has developed a lower cost dynamic glass technology that detects the amount of sunlight passing through a window and—when the window detects too much light—automatically tints itself to reduce unwanted glare.

The innovative technology was funded in part by the California Energy Commission’s Public Interest Energy Research (PIER) Program and is now commercially available.

The glass also reduces energy cost by enabling greater temperature control and blocking excessive heat, which mitigates the need for air conditioning on hot days.

In fact, a study from the Lawrence Berkeley National Laboratory shows that smart windows could reduce peak cooling loads by at least 19 percent and lighting loads by 48 percent. In existing commercial buildings, assuming a 10 percent market penetration, this technology could save California ratepayers more than 500 gigawatts a year, which translates to more than $65 million annually in lighting energy costs alone.

This technology has been installed in buildings throughout California, including the W Hotel in San Francisco and the Hilton Universal City in Los Angeles.

It is the latest example of how the Energy Commission is funding entrepreneurs and bringing technologies from “lab to life.”

Solar Energy Continues to Set Generation Records

There is a lot of record-setting going on as California continues to produce more and more solar energy.

A new study published by the U.S. Energy Information Administration (EIA) stated that total solar electricity output in May 2014 was three times what it was just one year ago, when measured as a percentage of the total California Independent System Operator (California ISO) electricity load. Solar accounted for 6 percent of the May 2014 load. It accounted for 2 percent of the May 2013 load.

The EIA also reported that on June 1 of this year the California ISO recorded a record midday hourly peak of 4767 megawatts of utility-generated solar electricity delivered in the California grid.

Note: Data do not include distributed generation solar electricity where output is behind-the-meter.
The report added the good news will continue through 2014 as utility-scale solar installations are expected to remain at a brisk pace because of declining solar manufacturing costs and the federal investment tax credit in place through the end of 2016.

New Title 24 Standards Take Effect July 1

Designed to get even more energy savings from new and existing residential and nonresidential buildings, California’s 2013 Building Energy Efficiency Standards (Title 24) take effect July 1.

The 2013 standards are a significant improvement over current ones adopted in 2008: they will reduce energy use by 25 percent in residential buildings and 30 percent in nonresidential buildings for lighting, heating, cooling, ventilation, and water heating.

The standards will result in buildings being more comfortable and will decrease energy costs. They also help reduce greenhouse gas emissions from a sector that accounts for 40 percent of emissions across the United States, according to the U.S. Green Building Council.

These standards set the foundation of California’s goal to have all new residential buildings be Zero-Net Energy by 2020 and all new nonresidential buildings be Zero-Net Energy by 2030.

The California Energy Commission – which proposed, adopted and is rolling out the standards – developed more sophisticated public domain compliance software that more accurately captures energy savings. The California Building Energy Code Compliance (CBECC) software is a free, open-source program that models residential and nonresidential buildings, giving businesses a better understanding of what is required to be in compliance.

CBECC software tutorial
The Energy Commission is working with the industry to make compliance as easy as possible. A series of webinars over the past six months gave an overview of updates on the changes and tutorials on how to use the CBECC software.

 Energy efficiency is one of the cheapest, fastest ways to reduce climate pollution and improve air quality.

Hyundai the First to Launch Consumer Line of Hydrogen Electric Fuel Cell Vehicles, in Southern California

In two more California firsts, a family in Southern California picked up the keys yesterday to their new hydrogen-fueled Hyundai Tucson. The Bush family was the first to buy a mass-produced hydrogen fuel cell electric vehicle (FCV) and Hyundai is the first automaker to launch a consumer fleet.

Like other electric vehicles, FCVs are zero-emission. FCVs can go further – 250-300 miles -- on a “tank” and come in bigger models, such as Tucson SUVs, but they require fueling stations.

With transportation accounting for 40 percent of California’s carbon emissions, creating a range of consumer choices is an important part of greening the transportation fleet in order to meet California’s goal to reduce greenhouse gas emissions.

Energy Commissioner
Janea A. Scott
The Energy Commission and the Air Resources Board are working together to build a network of 100 hydrogen fueling stations throughout California. A number of these will be found in regular gas stations so more families like the Bushes can easily refuel their vehicles.

The Energy Commission also recently announced $50 million in awards to build 28 new stations. The investments will help build 28 new stations and one mobile refueler, bringing the number of publicly available stations to 54.

Congratulations to Hyundai and the Bush family for being first out of the gate with this next-generation vehicle that will help California improve its air quality and continue setting an example for others to follow.
