Installing active solar energy systems on all available, unshaded rooftop
space and positioning them to face south.
<h3>What is a Solar system?</h3>
A solar system usually comprises of panels which help to collect solar
energy from the Sun and convert them to other forms of energy such as:
The Passive system optimizes the use of heat or light directly from the sun
while the active systems converts the sun's energy into a more usable form
such as electricity. It is also best to position the panels to face south
because the Sun is found at this region thereby encouraging maximum
trapping of solar energy.

Answer:
In the pre-classical age (8000 B.C.E. to 600 B.C.E.) the first states developed in core civilizations. Then, powerful cities imposed their rule on surrounding areas through conquest and the first empires were born. In the classical age (600 B.C.E. to 600 C.E.) empires grew on a massive scale through territorial conquest with large armies. The growing scale of these empires, along with their increased ethnic and cultural diversity, required more sophisticated methods of governance. They served as major hubs of transregional networks of trade, and they diffused culture, religion, technologies and disease. As empires acquired massive wealth, the unequal distribution of this wealth across social classes placed enormous pressure on the political and social order. Eventually, all of the classical civilizations could not deal with the problems created by their own internal or external crises. In most cases, the belief systems spawned in these empires left enduring cultural footprints even as the empires' political structures disintegrated.
