Trees help you, our city and the planet. They look attractive, their shade will keep your home cooler in the summer and trees sequester carbon while producing oxygen. Trees can play a pivotal role in the response to climate change and you can make a difference.
GreenTown Los Altos is happy to report we planted over 300 trees and we're ready to plant some more!
Check out the tree list prepared with the help of Canopy, and sign up for a visit from us. We'll come to your house and help you pick out a tree. The trees are in 15-gallon containers and we charge $110 per tree which includes the planting.
We think that's a pretty good deal and hope you will too!

Boosts kids’ confidence and fosters bonding with peers
Encourages a healthy, fit lifestyle
Reduces local school traffic, improving kids’ safety
The City of Los Altos is working to build a more sustainable bicycle and pedestrian safety education program in local schools. Visit Los Altos' Safe Routes to School page for more information. Options for good bike safety education include:
School Assemblies for Elementary Schools
Hands-on Bike Rodeos for 3rd and 4th Graders
Drive that Bike Classes for Junior High
Raising Safe Cyclists for all Parents
GreenTown also works with the Los Altos and Cupertino School Districts and Bullis Charter School to survey Los Altos/Hills’ student travel modes two to three times during the year. Findings include:
More students WoW! to school in upper grades: approx. 40% of 6th graders; more than 60% of 7th and 8th graders.
Junior High top the charts: approx. 65% of Blach and 45% of Egan students WoW! to school.
Elementary Schools with greater WoW! student populations have high parent involvement and active WoW! programs.
Fewer students WoW! to/from elementary schools with attendance areas on the other side of a major thoroughfare (e.g., Foothill or El Camino).
Blach Intermediate consistently has the highest WoW! rates.
A Walking School Bus is a great way to encourage a healthy and environmentally friendly way of getting to school. This type of program is perfect for younger children who need supervision. It can be easily organized by parents and take place once a week, a couple times a week, or even everyday!
Steps for Starting Simple:
Families in the same neighborhood decide to walk together to and from school.
A route is designed and tested by adults for safety. Don’t forget to record how much time the entire route takes. Refer to the list of maps above to determine the best route for your walking school bus.
The group decides how often to walk together. Consistent walking school buses are often the most successful.
Create a phone list to ensure that all children have emergency contact numbers.
Let the Walking School Bus begin! Get Started with this planning guide!
Similar to the Walking School Bus concept, a Bicycle Train is a group of neighbors that ride their bikes together to and from school. This program involves more planning and training since children must understand bicycle safety and how to ride on a road.
Basic Considerations:
Bicycle trains are best suited for older elementary children.
We recommend that you start out by providing your children with a basic understanding of the rules of the road and bicycle safety. Practice as a group and have several parents on hand to help demonstrate.
Every child must wear a bicycle helmet. Check to make sure that your child’s bicycle is working properly and is an appropriate size.
More adult supervision is needed than for Walking School Buses. Consider having one adult for every three to six children.
See Bicycling to School Together: A Bike Train Planning Guide for an example of steps to implementing a bicycle train in your neighborhood.
Application for the 2025 Internship is now Closed. Please check back in the Spring 2026 for the 2026 internship.
For 2025, we are offering four paid internships in two project areas. Each internship is for 10 hours/week for 6 weeks at $18.20/hour.

Electrifying your home is an important, rewarding process and a step towards a secure future. Here are some resources to read through for advice, tips, and recommendations.
Residential methane (aka gas) appliances make up nearly 32% of city-wide Greenhouse Gas Emissions
Studies show that we need 14 million more electric appliances nationwide to achieve net-zero emissions
Rising atmospheric concentrations of methane and CO2 affect our environment
From the Los Altos Climate Action and Adaption Plan : "Los Altos will experience increased heat waves, floods, drought, and poor air quality from regional events... and...impacts of climate change"
Heat Pump Space Heating
More efficient, which means you can save money on your energy bills.
Quieter, which can make your home more comfortable.
Longer lifespan, so you won't have to replace them as often.
Better for the environment, as they produce no emissions.
A heat pump system can multitask: heating, cooling, dehumidifying, and filtering the air.
This is your chance to get A/C if you haven’t already!
Heat Pump Water Heating
Over 3x efficient
For every 1 unit of electric energy input, a heat pump produces 3 to 4 units of energy output. So a heat pump can transfer 300-400% more energy than it consumes. Most methane gas-powered furnaces are 80% efficient, with those above 90% considered high efficiency.
Safer—zero risk of gas leaks
Consider replacing it if your current heater is over 6 years old
Especially consider replacement if you are currently using a gas tank less heater, which leaks twice as much methane as gas tank models do.
Induction Stoves
Gas stoves carry several health risks: poor indoor air quality with particles/carcinogens
Fans provided with gas stoves do not properly ventilate
Most of your pans should still be usable if they’re cast iron
Induction stoves:
heat faster than electric and gas counterparts
offer more precise temperature control
reduce the risks of burns since only the pan, not the cooktop heats up.
All-in-one Washer/Dryer
These can treat laundry gentler, prolonging life and maintaining quality of clothes
Is quieter and requires less space, maintenance
Ventless system, which is leads to lower construction costs and electricity bills
Lower priority, but still valuable modifications:
Fireplaces
Electric garden tools
Solar panels
SVCE supplies us with clean energy so solar panel installation is not required for electrification. It can, however, drive down operating costs over time, put less strain on the grid, and provide you with onsite battery backup.
What if my gas appliances are new and I don’t want to replace them?
Consider that embarking onto the electrification journey now will be taking advantage of peak rebate season and would lessen emissions immediately.
Try small swaps, like purchasing a stand-alone induction hot-plate for your kitchen to reduce some of your gas use and indoor pollution. Models are available for under $100. There are also hacks to make installation cheap.
As a renter, what can I do?
Approach your landlord with these electrification suggestions. Make sure to highlight that electrification makes buildings more attractive to future renters
Check out these suggestions: https://www.energy.gov/save/renters
What if electrifying seems too inconvenient for my home?
Arrange for an energy audit and work closely with professionals to find workarounds unique to your home. Consult our case studies for some examples.
How do heat pumps work?
Simply put: they use electricity to move heat around and use refrigerant to store and release heat in the cycle. Here is a breakdown by MIT Technology Review.
Ok, so they need refrigerant. What kind do they use?
Some units use naturally occurring CO2 refrigerants, which provide the lowest global warming potential (GWP). Others use synthetic hydrofluorocarbon (HFC) refrigerants, such as R410A or R134A. Here is a more in-depth overview addressing safety concerns. The EPA recently mandated that US manufacturers and importers reduce HFC use by 85% in the next 15 years, a move supported by virtually all US manufacturers. Climate-friendly alternatives to HFCs are increasingly available for most uses: natural or non fluorinated substances with low GWPs, and fluorinated substances with low to mid-range GWPs.
For any appliance that uses refrigerants, check regularly for leakage.
Won’t this further strain the grid?
Planned and existing distributed and grid-level storage will be able to take excess energy and use it to manage the energy needs for the hours of transition in load.
California itself has worked to meet this demand, increasing utility scale battery storage ten-fold in the last two years. This is how the state avoided major blackouts in the heatwave of Sept. 2022–the most severe ever recorded. That storage capacity is set to double again in the next few years.
The state has also planned for an additional 20 Gw of offshore wind capacity.
What if there’s an outage?
Install solar panels with a solar battery backup. The best solution for cases of power failure is an all electric home with onsite battery backup. That allows the home to operate without interruption. In the future companies are exploring the potential to use the batteries in your electric vehicle as an electricity source for your home in times of peak usage or outages.
It would also be possible to procure a solar-powered generator to keep critical appliances running during a power outage.
AVOID petroleum-powered generators due to fire risks and dangers from carbon monoxide poisoning in enclosed spaces.
Does electrification mean that I need to upgrade my electrical panel?
Not necessarily: upgrading your panel can be a costly disturbance. The majority of all electric homes should be able to run off a 200-amp service or less. It’s important to choose power efficient electric appliances and utilizing power sharing devices that monitor circuit usage and control the power delivered to shared devices. This may help you avoid upgrading the utility service line or your circuit breaker panel. More details are provided in the Watt Diet Calculator
Aside from electrification, how can I conserve energy?
PGE demand-response programs connect you with third party programs that allow customers to save or earn money by adjusting energy usage.
An example would be Ohm Connect
Put in a smart thermostat, an inexpensive solution that can save you money on your energy bills.
Make your ceiling/attic more energy efficient, using insulation to keep heat in during the winter, and attic fans to pull heat out during the summer.
Lower your energy bills and improve your air quality by repairing leaky air ducts.
If you have an EV, charge it during the middle of the day, when solar power is most abundant and sometimes over abundant. Your EV battery can store this “surplus” electricity, which would otherwise go to waste.
The US Department of Energy’s Home Energy Saver tool can also help you make a plan to improve your home’s building envelope.
Switch to LED bulbs, especially for the most commonly used bulbs.
Install outdoor shades or awnings, which can reduce solar heat gain by up to 65 percent on south-facing windows and 77 percent on west-facing windows
Plant a tree or shrubs to the west of your home to help keep it cooler.
You can get up to a 30% tax credit off a home energy audit via IRS Form 5695
SVCE’s FutureFitHomes allows you to receive up to 8,000 (up to 13000 if low-income qualifying)
this is a program applying only to heat pump appliances

Stack stack stack! Take advantage of all the rebates available now and apply several at the same time to shave down the price of electrification
Key takeaways from Redwood Energy's comprehensive guide to appliances:
When it comes to deciding between ductless and ducted space heating systems, split ductless heating can be more easily installed, provide advanced filtration, and is significantly cheaper
all in-one washer/dryers are the simplest upgrade, specifically 120v condenser washer/dryers, as they can be plugged into any 120v outlet
Get a heat pump water heater instead of a gas/electric tankless model, which can emit nearly twice as much gas as a normal gas tank model
120v heat pump water heaters are a new, extra-convenient option
If you don’t currently have electrical resistance water heating (which requires a 240v outlet), this would be much more accessible than a 240v model
Try local lending programs for induction stoves to see if your pans work! If they are cast-iron, they will most likely be fine.
Gas-powered leaf blowers are illegal in over 170 cities across the country because they are highly polluting, unhealthy, and noisy.
Gas-powered leaf blowers are bad for the environment and contribute to climate change. The California Air Resources Board states that by 2020, leaf blowers and other small gas engines will create more ozone pollution than all the cars in the state. For more information, please review this report by KQED News. Carbon monoxide, nitrous oxides, and hydrocarbons escape in large quantities from the 2-stroke engines of gas-powered leaf blowers. Oxides and hydrocarbons contribute to smog formation.
In a comparison with a Ford F-150 Raptor truck, the 2-stroke gas blower generated 23 times more carbon monoxide and nearly 300 times more non-methane hydrocarbons than the truck. https://www.edmunds.com/about/press/leaf-blowers-emissions-dirtier-than-high-performance-pick-up-trucks-says-edmunds-insidelinecom.html
California officials said that the contamination from running a top-selling leaf blower for just one hour matches the emissions from driving a 2016 Toyota Camry for 1,100 miles, the distance from Los Angeles to Denver. www.arb.ca.gov/msorog/offroad/sore/sm_en_fs.pdf
Gas-powered leaf blowers are unhealthy for everyone, particularly children, seniors, pets, wildlife and especially the operator. They generate two very significant health hazards: toxic emissions and particulate matter. The gas leaf blower 2-stroke engines disturb neighbors and disrupt our quiet neighborhoods. For more information, please take a look at this informative website.
Hydrocarbons can be carcinogens and nitrous oxides can cause acid rain. Health hazards of gas leaf blower use are documented by the American Lung Association, American Cancer Society, Bay Area Air Quality Management District and California Air Resources Board.
In addition to toxic emissions, leaf blowers blast particulate matter of fungi, pollen, spores, animal feces, pesticides, mold and more into the air. Exposure to particulate matter is an important contributing factor in hundreds of deaths in the Bay Area each year. (CAARB) Fine particulates measuring 2.5 microns and coarser materials measuring 10 microns are readily absorbed in the lungs. 2.5 microns can migrate hundreds of miles and stay in the air for days or weeks. Microns measuring 10 can travel up to 30 miles and stay aloft for hours. (USEPA)
Landscape experts advise: LEAVE THE LEAVES. Leaf blowers dry out garden soil, push mold, pollen, insect eggs, animal feces and more into the air and destroy habitats for wildlife. For more information, please read this informative article.
Let your gardener know about the ordinance. Purchase an electric blower and/or batteries for your gardener, or instruct that he/she use a rake and broom.
The use of gas leaf blowers is prohibited in Los Altos at any time. Fines for violations range from $100 to $500.
In 1991, Los Altos was the first city in the Bay Area to prohibit the use of gas leaf blowers. Recent changes to enforcement of this municipal code ordinance occurred in November 2022 when the responsibility for enforcement was moved from the Los Altos Police Department to the City staff. A new code enforcement officer was hired in April 2023. On July 11, 2023, the City Council approved a new “stand alone” ordinance (section 11.15) in the municipal code. The major change in the ordinance is to assign the responsibility of liability for the operation and use of a gas-powered leaf blower to the recorded property owner of the site where the violation has occurred.
You can help promote cleaner air in our community. Report the use of gas leaf blowers through the online complaint form, phone, or email.
