Many experts generally conclude that a combination of energy efficiency improvements and regulated use of will likely be the best way to make a transition from nonrenewable to using mostly renewable energy resources. wind power coal crude oil nuclear energy natural gas

## Step 1<br />The problem is asking us to identify the type of energy that, when used in a regulated manner, can help in the transition from nonrenewable energy sources to renewable ones. The options provided are wind power, coal, crude oil, nuclear energy, and natural gas.<br /><br />## Step 2<br />We need to consider the nature of each energy source. Wind power and nuclear energy are renewable energy sources, while coal, crude oil, and natural gas are nonrenewable.<br /><br />## Step 3<br />The question is asking for a nonrenewable energy source that can be used in a regulated manner to help in the transition to renewable energy sources. Therefore, we need to choose the option that is nonrenewable but can be used in a regulated manner.<br /><br />## Step 4<br />Among the options, natural gas is the most suitable choice. It is a nonrenewable energy source, but it can be used in a regulated manner to help in the transition to renewable energy sources.
