Comprehensive Analysis of Heating Sources for a 1500 Sqft House in Nova Scotia, Canada

Assumptions

  • Heating Load: 40,000 BTU/h

  • Heating Duration: 24 hours/day for 30 days (~720 hours per month)

  • Monthly Heating Requirement: 40,000 BTU/h × 720 hours = 28.8 million BTU/month

  • Heating Season Duration: 7 months (late October to early May)

1. Electricity Heating

Monthly Cost Calculation:

  • Effective energy required: (28.8 million BTU / 0.95) = ~30.32 million BTU

  • Propane required: (30.32 million BTU / 23.65 million BTU/1,000 liters) = ~1,283 liters

  • Monthly cost: 1,283 liters × $1.30/liter = $1,668.16

Annual Cost Calculation:

  • Annual cost: $1,668.16 × 7 months = $11,677.12

Monthly Cost Calculation:

  • Energy required: (28.8 million BTU / 3) = ~9.6 million BTU

  • Energy in kWh: (9.6 million BTU / 3,412 BTU/kWh) = ~2,813 kWh

  • Monthly cost: 2,813 kWh × $0.1227/kWh = $345.20

Annual Cost Calculation:

  • Annual cost: $345.20 × 7 months = $2,416.40

Power to the People: Exploring Home and Small Business Energy Solutions. Can Your Home or Business Become Its Own Power Plant?

Listen to this article in audio The Power at Your Fingertips: Homes and Businesses Generating Their Own Energy. Power in Your Hands: How Homes and Small Businesses Can Save Money and Cut Emissions. Should Homes and Businesses Build Their Own Power Plant? An In-Depth Look at ROI, Savings, and the Future of On-Site Power Generation Introduction The idea of producing your own electricity and heat on-site, essentially building a “micro power plant” for your home or business, sounds futuristic, but it is becoming increasingly realistic. With energy prices rising, grid reliability concerns growing, and governments offering incentives for efficiency and emissions reductions, many are asking: is it possible, and worthwhile, to run your own private power plant? For certain types of properties, such as large homes with high energy needs, hotels, manufacturing facilities, or commercial buildings, the answer may be yes. By combining a natural gas–powered generator (genset) or microturbine with a h...

Energy Didn’t Make Us Poor — Government Decisions Did

  Listen to this article in audio Energy Was the Excuse. Policy Was the Cause Energy Didn’t Make Us Poor — Policy Did How monetary expansion, market concentration, and regulatory layering drove Canada’s cost-of-living crisis, while energy took the blame. You’ve been told it was energy that made your groceries cost more. You’ve been told it was oil that made your rent skyrocket. You’ve been told it was “inflation,” and there’s nothing you could do. But the truth is far harsher: energy did not betray you. The problem is the system built around it. Money printed without restraint. Regulations are layered on top of every expense. Giant corporations are using every opportunity to raise prices while your wages barely move. This is not an accident. This is not a mystery. This is how your cost of living got hijacked. And why it will continue to rise until we understand the real forces at work. ENERGY DID NOT CAUSE YOUR COST-OF-LIVING CRISIS Stop Blaming the Barrel Energy prices didn...
