As the saying goes: nothing is new under the sun. Regarding this proverbs, there are two factors I may consider. For one thing, all things exist on the earth are rely on the solar energy to some extent, even the conventional resource such as coal, fossil and petroleum are indirectly produced by solar energy. For…
Energy saving is more and more popular. We have no idea about consumption of electricity until we get the bill. So it’s more and more popular to get a device and app to monitor our home appliance. For now, we have wireless energy monitor for energy monitoring and looking for APP software provider. Which country…
