Step-by-Step Guide

1. Audit Your Home Energy Use

The average Denver household emits approximately 10 metric tons of CO₂ annually, with nearly half of that coming from natural gas and electricity used for heating, cooling, and appliances. The first step toward reducing your carbon footprint is understanding where your energy is going.

Start by requesting a free home energy audit from Xcel Energy, Denver’s primary utility provider. Their program includes a professional assessment of insulation levels, HVAC efficiency, air leakage, and appliance performance. Many residents qualify for rebates of up to $1,500 for upgrades recommended during the audit.

Alternatively, use a smart energy monitor like Sense or Emporia Vue to track real-time electricity consumption. These devices connect to your breaker panel and identify energy-hungry appliances—often revealing that old refrigerators, inefficient water heaters, or phantom loads from standby electronics are draining power even when unused.

Once you’ve identified inefficiencies, prioritize upgrades based on return on investment. Insulating your attic and sealing ductwork can reduce heating demands by up to 20%, especially critical in Denver’s cold winters. Replace single-pane windows with ENERGY STAR-certified double-pane models—many local contractors offer discounts through state-funded programs.

2. Transition to Renewable Energy

Denver has some of the most favorable solar conditions in the country, averaging over 300 days of sunshine annually. Switching to solar power is one of the most impactful steps you can take.

Enroll in Xcel Energy’s Solar*Rewards program, which provides cash incentives of $0.15–$0.25 per kilowatt-hour generated for the first 10 years. If you own your home, consider installing rooftop solar panels. Federal tax credits currently cover 30% of installation costs through the Inflation Reduction Act, and Colorado offers an additional state tax credit of up to $5,500.

Not ready for panels? Join the community solar program. Xcel Energy and other providers like Arcadia and Clean Energy Collective offer subscriptions to off-site solar farms. You pay a monthly fee based on your energy usage and receive credits on your utility bill—no installation required. This option is ideal for renters, condo owners, or those with shaded roofs.

For those who prefer wind energy, Xcel’s Windsource program allows you to opt into 100% wind-powered electricity for a small premium—typically less than $10 extra per month.

3. Upgrade to Electric or High-Efficiency Heating

Denver’s cold winters mean heating accounts for nearly 40% of residential energy use. Natural gas furnaces are common but emit significant CO₂. Replace them with a heat pump.

Modern air-source heat pumps are now efficient even in sub-zero temperatures. The latest models operate effectively down to -15°F, making them ideal for Denver’s climate. They provide both heating and cooling, replacing your furnace and air conditioner in one unit.

Through the Colorado Energy Office’s Home Energy Rebate program, residents can receive up to $8,000 in rebates for installing a heat pump. Additional incentives are available through local utilities and nonprofit organizations like the Colorado Energy Efficiency Alliance.

If a heat pump isn’t feasible yet, upgrade to a high-efficiency gas furnace (95%+ AFUE rating) and install a programmable or smart thermostat. Nest or Ecobee thermostats learn your schedule and adjust temperatures automatically, reducing heating and cooling by 10–12% annually.

4. Reduce Water Heating Emissions

Water heating is the second-largest energy expense in most Denver homes. Switching to an electric heat pump water heater (HPWH) can cut energy use by 60% compared to traditional electric or gas models.

HPWHs work like reverse air conditioners, extracting heat from surrounding air to warm water. They’re especially efficient in basements or garages where ambient temperatures remain above 40°F—common in Denver homes.

Rebates of up to $1,750 are available through Xcel Energy’s HPWH program. Some municipalities, including Boulder and Golden, offer additional local incentives. Combine this with low-flow showerheads and faucet aerators to reduce hot water demand by 30–50%.

For those who prefer gas, install a condensing gas water heater with an efficiency rating of 90% or higher. Insulate your existing water heater tank and pipes if replacement isn’t immediate.

5. Electrify Your Transportation

Transportation is Denver’s largest source of carbon emissions, accounting for over 35% of the city’s total. The good news? Denver has one of the most advanced public transit networks in the Mountain West, and EV adoption is accelerating rapidly.

Consider replacing your gasoline-powered vehicle with a plug-in hybrid (PHEV) or fully electric vehicle (EV). Colorado offers a $5,000 state tax credit for new EV purchases and $2,500 for used EVs under $50,000. Federal tax credits of up to $7,500 may also apply.

Denver’s public charging infrastructure has expanded dramatically. Over 1,200 public charging stations are now available across the metro area, including fast chargers along I-25, in downtown parking garages, and at major grocery stores like King Soopers and Whole Foods. Use apps like PlugShare or ChargePoint to locate stations near you.

For those who can’t afford a new EV, consider car-sharing services like Zipcar or Turo, which offer electric models. Or join a carpool through the Regional Transportation District’s (RTD) GoPass program, which provides free transit passes to commuters who carpool or use public transit.

6. Optimize Your Commute

If you’re not ready to go electric, make your daily commute greener by leveraging Denver’s transit network. RTD operates light rail, buses, and commuter rail lines connecting Denver to Aurora, Lakewood, Golden, and even Boulder.

Download the RTD app to plan routes, buy digital tickets, and track real-time arrivals. Many employers in Denver offer subsidized transit passes—check with your HR department. If you bike, take advantage of Denver’s 225+ miles of bike lanes and trails, including the popular Cherry Creek Trail and the High Line Canal.

Denver’s B-cycle bike-share program has over 200 stations across the city. A monthly membership costs just $15 and includes unlimited 45-minute rides. For longer trips, consider an e-bike. Colorado offers a $500 rebate on e-bike purchases through the state’s Clean Transportation Incentive Program.

Work from home at least one day a week if possible. Denver has one of the highest remote work adoption rates in the nation—reducing your commute even once a week can cut your transportation emissions by 20% annually.

7. Eat Sustainably and Reduce Food Waste

The food system contributes nearly 25% of global greenhouse gas emissions. In Denver, where farm-to-table culture thrives, you have unique opportunities to eat lower on the carbon ladder.

Reduce meat consumption, especially beef and lamb, which have the highest carbon footprints. Try “Meatless Mondays” or adopt a flexitarian diet. Denver has over 500 vegetarian and vegan restaurants, from the iconic Veggie Grill to the plant-based gourmet at Root Down.

Shop locally. Visit farmers markets like the Denver Union Station Farmers Market or the South Pearl Street Farmers Market. Local produce requires less transportation and refrigeration. Look for seasonal items like Colorado peaches, beets, and apples.

Compost your food scraps. Denver’s curbside compost program collects food waste, yard trimmings, and compostable packaging. Sign up for free through the city’s Solid Waste Management department. If you live in an apartment, join a community composting site like the Denver Composts program, which offers drop-off locations and educational workshops.

Avoid single-use plastics. Carry a reusable water bottle—Denver’s tap water is among the cleanest in the U.S. Use cloth bags, beeswax wraps, and glass containers instead of plastic wrap and bags.

8. Reduce, Reuse, Recycle—Mindfully

Recycling alone won’t solve Denver’s waste problem. The most effective strategy is reducing consumption in the first place.

Buy secondhand. Denver has thriving thrift scenes—from the massive Goodwill stores on Colfax to boutique consignment shops in Capitol Hill and RiNo. Platforms like Facebook Marketplace, Craigslist, and Letgo make it easy to find furniture, electronics, and clothing locally.

Repair instead of replace. Visit the Repair Café Denver, a volunteer-run event held monthly where experts help you fix broken items—from toasters to bicycles—for free. The city also hosts “Fix-It Fairs” twice a year at community centers.

Recycle correctly. Denver’s single-stream recycling program accepts paper, cardboard, metal, and certain plastics (

1 and #2). But contamination is a major issue. Rinse containers, remove lids, and never bag recyclables. Learn what not to recycle: plastic bags, styrofoam, and greasy pizza boxes go in the trash.

Participate in hazardous waste drop-offs. Paint, batteries, electronics, and chemicals should never go in regular trash. The City of Denver’s Household Hazardous Waste Facility accepts these items for free at 10100 W. 48th Ave.

9. Advocate and Engage in Community Action

Individual actions matter, but systemic change requires collective voice. Get involved in Denver’s environmental initiatives.

Join the Denver Climate Action Network, a coalition of residents, nonprofits, and businesses pushing for equitable climate policies. Attend City Council meetings and speak in support of green building codes, expanded public transit, and renewable energy mandates.

Support local climate policies like Denver’s Climate Action Plan, which aims for 80% emissions reduction by 2050 and 100% clean electricity by 2030. Urge your city councilmember to prioritize tree planting, green roofs, and urban heat island mitigation.

Volunteer with organizations like Trees for Denver, which plants and maintains over 10,000 trees annually. Trees absorb CO₂, reduce urban heat, and improve air quality. You can even request a free tree for your yard through their program.

10. Monitor Your Progress

Tracking your impact keeps you motivated and helps you refine your strategy. Use free carbon footprint calculators like the EPA’s Personal Emissions Calculator or CoolClimate Network’s tool, which includes location-specific data for Denver.

Set quarterly goals: “Reduce electricity use by 15%,” “Cut car trips by 50%,” or “Compost 100% of food waste.” Celebrate milestones and share your journey with friends. Social accountability is a powerful motivator.

Many Denver residents use apps like Oroeco or JouleBug to gamify sustainability—earning points for biking, recycling, or eating plant-based meals. These apps connect you to local challenges and rewards, making green living fun and social.

Best Practices

Start Small, Think Long-Term

Don’t try to overhaul your life overnight. Focus on one high-impact change at a time. Replacing a single incandescent bulb with an LED saves 75% energy and lasts 25 times longer. That’s an easy win. Once you’ve mastered one habit, layer on another.

Align with Denver’s Climate Goals

Denver’s Climate Action Plan prioritizes equity, resilience, and community engagement. Prioritize actions that support these pillars: choose public transit over ride-hailing, support local businesses with green certifications, and advocate for low-income energy assistance programs.

Seasonal Adjustments Matter

Denver’s weather swings dramatically. In winter, lower your thermostat by 7–10°F when you’re asleep or away. In summer, use ceiling fans and close blinds during peak sun hours. These simple habits can reduce HVAC load by 10–20% without sacrificing comfort.

Invest in Quality, Not Quantity

Choose durable, repairable goods over cheap, disposable ones. A $300 insulated water bottle that lasts 10 years is far better than 20 disposable plastic bottles a year. This reduces both emissions and landfill waste.

Engage Your Workplace

Encourage your employer to adopt green practices: install motion-sensor lighting, provide recycling bins, offer transit subsidies, or host a “green team.” Many Denver companies are eligible for Green Business Certification through the Colorado Green Business Program.

Use Natural Cooling and Heating

Denver’s dry climate allows for effective passive design. Open windows at night in spring and fall to cool your home naturally. In winter, open south-facing blinds during the day to capture sunlight. These strategies require no energy and reduce reliance on mechanical systems.

Choose Green Energy for All Appliances

Even small devices add up. Use a smart power strip to eliminate phantom loads from TVs, chargers, and gaming consoles. When replacing appliances, always choose ENERGY STAR models. They use 10–50% less energy than standard versions.

Build Community Resilience

Organize a neighborhood energy swap: trade tips, tools, or even solar panel installations. Create a “tool library” where residents borrow lawnmowers, pressure washers, or ladders instead of buying new ones. Shared resources reduce consumption and strengthen community bonds.
