Economic factors play a big role in choosing materials for sustainable design. This means deciding between renewable resources, like trees, and non-renewable resources, like fossil fuels. Here are some important points to think about:

1. Cost of Materials:

   • Right now, non-renewable resources, like fossil fuels, are often cheaper to get. For instance, in 2020, coal in the U.S. cost around $35 for each ton.
   • On the other hand, renewable materials, such as wood and bioplastics, usually cost more, averaging between $50 and$70 per ton. The good news is that these prices are going down as technology gets better.

2. Lifecycle Costs:

   • Renewable resources often save money in the long run when it comes to energy use. Studies show that using renewable energy can cut energy costs by more than 50% over time.

3. Regulatory Impacts:

   • The government is encouraging the use of renewable materials, which can help lower upfront costs. In 2022, the U.S. set aside over $20 billion for green energy programs.

4. Market Demand:

   • More people are wanting sustainable materials, which helps raise their market value. This change affects how practical and profitable these materials are.

In summary, while non-renewable resources might be cheaper now, renewable materials are becoming more affordable and valuable thanks to technology and growing public interest.
