How to Create a Smart, Energy-Efficient Apartment for Under $100

Energy efficiency and smart living go hand in hand, especially for renters who want to maximize comfort, reduce utility costs, and help the planet — all without making permanent changes to their space or breaking the bank. The good news? You don’t need a huge budget or own your home to make significant improvements. With less than $100 and a few practical gadgets, you can create a smart, energy-efficient apartment that saves money and feels great to live in. Here’s how.

Why Focus on Energy Efficiency in Your Apartment?

• Lower utility bills: Save money every month by using less energy.
• Reduced environmental impact: Less energy means a smaller carbon footprint.
• Improved comfort: Smarter controls keep your home at the perfect temperature and lighting.
• Easy upgrades: Most simple, renter-friendly solutions require no rewiring or landlord approval.

Step 1: Assess and Track Your Energy Use

Before you start buying gadgets, take a little time to understand where your energy goes.

Quick Apartment Energy Audit

• Identify old or inefficient appliances and light bulbs.
• Look for drafts near windows and doors.
• Note which devices are always plugged in (even when not in use).
• Track energy use using your utility bills.

Awareness helps you prioritize what to upgrade first for the best results.

Step 2: Invest in Smart, Plug-and-Play Devices

Smart home technology isn’t just for homeowners. Many renter-friendly options are self-install, work with your Wi-Fi, and don’t require rewiring. Here are the most effective ways to get started — all for under $100 total.

1. Smart Plugs

• Why: Smart plugs let you control lamps, fans, and appliances from your phone or voice assistant. Set schedules to avoid wasted energy and automate routines.
• Cost: $10-20 for a two-pack.
• Where to use: Entertainment systems, kitchen appliances, space heaters, and anything that draws power when not in use.

2. LED Smart Bulbs

• Why: Replace energy-guzzling incandescents with LED smart bulbs. Customize brightness, color, and schedule remotely for both savings and ambiance.
• Cost: $15-30 for a 2-pack.
• Tip: Even if you can’t replace every bulb, targeting fixtures you use most can pay off quickly.

3. Simple Door & Window Draft Stoppers

• Why: Drafts around doors and windows lead to energy waste. Soft foam or fabric stoppers require no installation and seal that expensive air inside.
• Cost: $7-15 each.
• Renter-friendly: No adhesives or screws needed.

4. Affordable Smart Thermostats (Plugin Models)

• Why: If your apartment uses plug-in space heaters or AC units, a smart thermostat plug allows smartphone and schedule-based temperature controls — no wiring or landlord approval.
• Cost: $20-40.
• Pro tip: Check for compatibility with your device (most work with portable heaters and window ACs).

5. Energy Usage Monitors

• Why: Plug these devices into your outlets to see, in real-time, how much electricity each appliance uses. Spot the biggest “energy vampires” and unplug or automate as needed.
• Cost: $15-20 per unit.

Step 3: Setup and Automate for Maximum Savings

Devices alone aren’t enough — the real magic is how you use them. Let’s see how to put your new gadgets to work.

Automate Your Lighting

• Set smart bulbs and plugs to turn off automatically when you leave for work or go to bed.
• Use voice commands or a simple tap on your smartphone to control devices without even getting off the couch.
• Try motion detector features (built into some smart bulbs) for closets and hallways.

Kill “Energy Vampire” Devices

• Many TVs, game consoles, and kitchen gadgets draw power even when switched off. Plug them into a smart plug, and schedule it to turn off when not in use.
• Use energy monitors to find the worst offenders.

Smart Temperature Control

• Pair plug-in thermostats with portable heaters or AC units. Program them to run only when needed, and turn off automatically when you leave the apartment.
• Even a 1-degree adjustment can save up to 10% on heating/cooling bills over time.

Block the Drafts

• Use draft stoppers at doors and windows in winter and summer for less heat/cold transfer.
• Removable thermal curtains can provide bonus insulation, but may put you over $100 depending on your needs. Prioritize for the coldest months.

Step 4: Combine and Conquer—Example $100 Smart Apartment Shopping List

• Smart Plugs (2-pack) — $15
• LED Smart Bulbs (2-pack) — $18
• Energy Usage Monitor — $17
• Door Draft Stopper — $9
• Smart Thermostat Plug — $25
• Total = $84 (prices may vary, but this shows it’s possible!)

Customize to fit your biggest needs — for example, more bulbs if you have many lamps, or extra draft stoppers for multiple doors.

Tips for Renters: Maximize Smart Upgrades Without Breaking Lease Rules

• No drilling or rewiring: All the gadgets listed here are plug-in or removable. Read manufacturer instructions and your lease agreement, but you rarely need permission.
• Choose removable adhesive hooks or velcro if mounting small sensors or smart device controls.
• Keep original equipment: Save any bulbs or hardware you swap out, so you can reinstall them before moving out.
• Ask about rebates: Some energy providers offer instant discounts for LED bulbs, smart plugs, or energy monitors. Check your local utility’s website.

Going Further: Low-Cost, No-Tech Solutions

If you have a little budget left or just love DIY:

• Weatherstripping tape: $5-10 per roll, seals cracks around windows/doors.
• Thermal curtains or shades: Block heat in summer/cold in winter. Starting at around $20.
• Reflective window film: Reduces heat gain in sunny windows for less than $15.
• Power strip with a timer: Set “off” hours for chargers and entertainment systems.

Bonus Tips: Eco-Friendly Routines for Big Results

• Laundry: Wash with cold water, and always run full loads. Hang-dry when possible.
• Dishes: Scrape, don’t rinse; run full loads in dishwashers on eco mode.
• Fan instead of AC: Use portable fans, and rotate to use cross-breezes. Fans use a fraction of the energy of AC units.
• Layer up or down: Wear season-appropriate clothes and use throw blankets before kicking up the heat or AC.
