Many notable chefs are touting the superiority of electric induction cooktops over polluting, wasteful gas ranges. For those of us who are just trying to get dinner on the table, a less-expensive electric range is usually fine.

• Replace natural gas ranges with electric.
• Use the least energy-intensive methods to cook. Ovens and stovetops require the most energy; microwave ovens, electric kettles, and toaster ovens require less. In the summer or in especially sunny areas, use an easy-to-build solar oven!
• Keep the freezer and fridge full for more efficient cooling. Crumpled newspaper is an inexpensive and effective way to fill in gaps in the freezer.
