There are a lot of benefits to using renewable energy. First, naturally replenished energy resources are found over wide geographical areas, in contrast to non-renewable resources, which exist only in a limited number of countries. In addition to that, rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits. The results of a recent review of the literature concluded that as greenhouse gas emitters begin to be held liable for damages resulting from greenhouse gas emissions resulting in climate change, a high value for liability mitigation would provide powerful incentives for deployment of renewable energy technologies.
There are other undeniable advantages of renewable energy. Renewable technologies are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Former United Nations Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity. Besides, as most renewables provide electricity, renewable energy deployment is often applied in conjunction with further electrification, which has several benefits:

Whales are mammals, so in many ways, they are just like human beings. The most important difference is that humans and whales live in different environments and whales have a special respiratory system that enables them to stay underwater for several minutes without breathing oxygen. For this reason, they are said to be voluntary breathers. That is, because of whales underwater environment, they must be conscious breathers. They think about every breath they take and come up to the surface of the water to breathe through blowholes on top of their heads.

And here whales sound odd.

Using is the way I probably would say it, as would many American speakers. Grammatically one might prefer to be using, but the word be is typically dropped in colloquial usage.

In the first one, using is the correct form of the verb for that sentence.

In the second one, it it supposed to be a plural possessive, so the correct word is "whales'"
