Take for example you do not want to go too deep into the idea of going green, you could start with light bulbs. Get those light bulbs that will save energy and in that regard reduce your power bills. If you were thinking of generating energy, you will need much more.
Step 2 - Budget your finances well. There is stuff that will often cost more in the short term. However, if you consider the long-term effect, you will notice that they are actually saving you money in the end. Budget to save money not overspend.
Step 3 - Have a savings account. This will make sure that your transition to the alternative lifestyle is tenable. You should not run into a brick wall headfirst. Most of the purchases are best done through savings. Say for example, you could save money in small bits until it accumulates.
Step 4 - Include your family members. You cannot be doing things alone behind the scenes. You cannot be the green guy yet your family does stuff that nullifies all that. You need to be at tandem and negotiate to move in one direction.
In their day, a family that has agreed to go green will be able to make each member agree with it in wholesale.
Step 5 - Start the Green lifestyle. Go round, shop for the energy panels, and have your gas-guzzler checked. Start buying energy efficient electronics and you are well on track.
