Switch your lights to LED lighting

LEDs are highly efficient compared to most light sources, losing very little energy as heat. According to the U.S. Department of Energy, LED bulbs use at least 75% less energy and last 25 times longer than incandescent lighting. The BBC reported that households switching to LEDs can reduce energy usage by up to nearly 90%.

Unplug appliances when not in use

The NRDC reports that inactive devices in homes waste significant amounts of electricity — costing U.S. consumers $19 billion annually. Around 23% of household electricity comes from devices on standby: televisions, cable boxes, printers. Using advanced power strips can save households 5–10% on energy bills.

Seal your windows and doors

Air leaks can account for up to 30% of heating and cooling energy. According to The Washington Post and the Energy Department, simple fixes like sealing windows and doors can reduce overall energy consumption by 5–20%. Caulking leaks alone can save an average household 10–20% on annual heating and cooling bills — around $166 a year.

Switch to more efficient products

Upgrading to energy-efficient appliances and smart devices makes a significant long-term difference. Read our companion article Low/saving energy products for a full breakdown of what to buy and what it costs.

Choose Efficient Transportation

Transportation accounts for 75% of tourism's carbon footprint. Opt for public transport or trains, which emit significantly less CO₂ per passenger-kilometre compared to cars and flights. For air travel, choose non-stop flights to reduce emissions by up to 25%.

Pack Light

Every extra 10 kg of luggage increases a vehicle's fuel consumption by 1–2%. Pack versatile clothing and multi-purpose items to reduce weight and energy use.

Stay in Energy-Efficient Accommodations

Hotels contribute 20% of tourism's emissions. Choose eco-certified accommodations, which use up to 25% less energy — and turn off lights and AC when not in the room.

Eat Smart

The global food system accounts for 26% of emissions. Eat local foods to reduce transport energy, and choose plant-based meals — which can save up to 80% of the energy required for meat-based diets.

Reduce Single-Use Plastics

Producing a single plastic bottle emits 0.3 kg of CO₂. Use reusable water bottles and utensils, and go paperless with digital tickets and maps.

Choose Low-Impact Activities

Walking or cycling reduces emissions to virtually zero. Engage in eco-friendly tours or conservation activities to support local ecosystems and offset your footprint.

Mind Your Digital Use

Streaming and cloud storage consume significant energy. Download content ahead of time, use offline modes, and unplug devices once charged — cutting energy use by up to 30%.

Offset Your Carbon Footprint

For unavoidable emissions, invest in carbon offsets — about $10–20 per ton of CO₂ — or support local environmental initiatives like reforestation.

LED Light Bulbs

The average cost for a 12W LED light bulb is $6.25. Even though LED bulbs are more expensive than traditional light bulbs, they use up to 75% less energy and last far longer — significantly reducing both your electricity bill and replacement costs over time.

Solar-Powered Items

Solar-powered chargers typically range from $20 to $100. Larger solar panels for residential use are more of an investment but deliver long-term savings. Solar-powered chargers are an accessible entry point — great for travel and outdoor use.

Smart Thermostats

In Indonesia, the market for smart thermostats is expanding rapidly due to growing demand for energy-efficient solutions. Products like Google Nest and Ecobee let users manage heating and cooling systems more efficiently — reducing energy consumption while maintaining comfort.

Smart Power Strips

Smart power strips automatically cut power to devices in standby mode. According to the NRDC, this simple switch can save up to 10% on electricity bills. Average cost: $10 to $15 — one of the best value-per-dollar energy upgrades you can make at home.
