Sustainable energy policy
Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy and are high priorities in the sustainable energy hierarchy.

Renewable energy
Any energy resource that is naturally regenerated over a short time scale and derived directly from the sunlight, wind, rain, tides, waves and geothermal heat.

Basics of Energy Use
Energy is a part of everything we do.
![Page 26: Energy efficient products (1)](https://reader035.fdocuments.net/reader035/viewer/2022081521/588445de1a28aba8438b60a7/html5/thumbnails/26.jpg)
Efficiency of Energy Conversion
If we are more efficient with the energy we already have there will be less pollution, less reliance on foreign oil and increased domestic security.

Illustration
An electric motor consumes 100 watts (a joule per second (J/s)) of power to obtain 90 watts of mechanical power. Determine its efficiency ?
= 90 W x 100 = 90 % 100 W

Vehicle Efficiency – Gasoline Engine
25% Of the gasoline is used to propel a car, the rest is “lost” as heat. i.e an efficiency of 0.25
![Page 32: Energy efficient products (1)](https://reader035.fdocuments.net/reader035/viewer/2022081521/588445de1a28aba8438b60a7/html5/thumbnails/32.jpg)
Energy-efficient products
Products/appliances can account for up to 30 per cent of your home energy use. As our reliance on products/appliances increases and energy prices are also on the rise, choosing energy-efficient appliances becomes more important. The national standards for energy efficiency are improving the environmental performance of appliances all the time, so upgrading to a more efficient appliance can save you energy and money.
![Page 33: Energy efficient products (1)](https://reader035.fdocuments.net/reader035/viewer/2022081521/588445de1a28aba8438b60a7/html5/thumbnails/33.jpg)
Energy Efficient Products
It's not only about having the right product—how you use appliances in your home can make a big difference. For example washing your clothes with warm water can save up to 10 times more energy than a cold wash
![Page 34: Energy efficient products (1)](https://reader035.fdocuments.net/reader035/viewer/2022081521/588445de1a28aba8438b60a7/html5/thumbnails/34.jpg)
WHAT IS YOUR AVERAGE MONTHLY ENERGY BILL?
Heating and cooling costs the average homeowner about $1,000 per year – nearly half the home’s total annual energy bill. Depending on where you live, replacing your old heating and cooling equipment with energy efficient products can cut your annual energy bill by more than $200.
![Page 35: Energy efficient products (1)](https://reader035.fdocuments.net/reader035/viewer/2022081521/588445de1a28aba8438b60a7/html5/thumbnails/35.jpg)
Think long term.
Many of the most energy-efficient products cost more initially, but they'll save you money in the long run. Expect to keep most major appliances between 10 and 20 years.
A more efficient appliance soon pays for itself; lower monthly utility bills over the lifetime of the appliance will more than offset a higher purchase price.
![Page 36: Energy efficient products (1)](https://reader035.fdocuments.net/reader035/viewer/2022081521/588445de1a28aba8438b60a7/html5/thumbnails/36.jpg)
Think long term.
In addition, the latest resource-efficient clothes washers and dishwashers not only save electricity, they also use a lot less water and can reduce your water bill.
