   nobody can change other people’s country there is a equator which tells us that the country that lives in the equator, has a hot climate, like Philippines,there are 4 kinds of climate one is north pole, next tropic of cancer, next equator, next tropic of Capricorn, and last south pole.

   Renewable sources include biomass, wave energy, wind power, geothermal, and solar power. The advantage of using biomass instead of fossil fuels is that that CO2 is currently in circulation in the atmosphere and is not being reintroduced as the fossil fuels are. Wind, water, solar, geothermal are all capable of sustaining humankind with all the energy we ever need. We are also pretty close of having good means of extracting the energy from these sources. The main drawbacks are a restructure of our current infrastructure to replace the fossil fuels, and the fact they lack in durability. Fossil fuel, or nuclear power goes right on 24/7. But winds, solar, and wave energy don’t have that durability. There will be fluctuations unless we can store the energy effectively in the available power.

   The effects of climate is an impact to renewable energy, Its like a bunch of windmills get built and start supplying power to the grid but because of natural variability in the wind they don’t provide that power all the time nor can we control when they provide their power so to use wind power you need a source of backup power that is reliable and usually that means fossil fuels. Solar is less variable but PV cells cost a lot more and it still needs backup at night and partial backup on cloudy days. The need for backup means that the fossil fuel industry still gets to exist
