Recycling Tips:
  • Clean containers before recycling
  • Check local recycling guidelines
  • Recycle electronics at special sites
  • Flatten cardboard boxes to save space
  • Consider upcycling before recycling

Solar Savings Calculator

Calculate potential savings from installing solar panels on your home. Find out system size, costs, and payback period. Average solar installation costs $15,000-$25,000 before incentives.

Solar Installation Tips:
  • Get multiple quotes from certified installers
  • Check roof condition before installation
  • Understand local net metering policies
  • Consider battery storage options
  • Monitor system performance regularly

Wind Power Calculator

Evaluate the potential for small-scale wind power generation at your location. Wind power needs consistent speeds of 10+ mph to be effective. Most residential installations require significant space and investment.
Check your local wind speed data online or with weather services Average wind speed at your location (mph) - need 10+ for viability

Wind Power Tips:
  • Wind speeds of 10+ mph needed
  • Check local zoning laws
  • Consider noise impact
  • Regular maintenance is crucial
  • Hybrid solar-wind systems work well

Composting Calculator

Calculate how much organic waste you can compost and the benefits. Composting reduces methane emissions from landfills and creates valuable soil amendment. About 30% of household waste can be composted.
Food scraps that can be composted Number of people in your household Pounds of food scraps per person per week (fruit peels, vegetable waste, coffee grounds)
Additional organic materials Pounds of yard waste per week (leaves, grass clippings, small branches) Percentage you actually compost (0-100%) - many people start at 50%
