Transportation is nearly a third. Of that personal vehicles are only around 10%.
So buying an electric car is wholy ineffective as most of the emissions are being cranked out buy heavy trucks, planes and trains.
Agriculture is 11% so eat whatever you want it won't make a difference, if you eat a "climate friendly diet" you're getting more of your fresh green food shipped by air from south America or pacific islands. So most of whatever you think you'll save there is just going towards burning jet fuel.
Biggest energy user in homes is an electric vehicle if you have one and HVAC. For me I burn fire wood so I use hardly any electricity during the winter. If I didn't have my leaf my power bills would be about $30, 2/3 of that being the service charge.
For summer I have split air conditioners so I only cool 0 to 2 rooms of my house, weturn it off during the day while where away. The splits can cool down a hot living room in about 10 minutes. About 28 out of 30 days a month my central A/C stays off.
The splits and wood stove save hundreds of dollars per month in electricity during the summer an winter.
