Dangerous heat waves are noticeable in some places. A heat wave is a prolonged period of excessive heat, often combined with excessive humidity. Extreme heat can cause cramps, swelling, and fainting. In July 1995, Chicago, Illinois experienced a heat wave that caused over 700 deaths. Scientists predict that the Midwest could endure similar heat waves up to 3 times a year by 2100 if greenhouse gas emissions continue to increase. They also cause blackouts and power outages. There have also been a growing number of large wildfires, which sends more CO2 into the atmosphere. Many places in the world are experiencing severe droughts. In May 2015, around 93% of California was in severe drought or worse. This shortage of water does not entirely depend upon the weather, but the society plays a role in it too. Everything is interconnected. The wildfires may lead to droughts, or sometimes the droughts lead to the wildfires. This places a huge risk on the human race as we cannot survive without water or …show more content…
Energy efficiency technologies allow us to use less energy to get the same level of production, comfort, and service. This approach has vast potential to save both money and energy, and can be deployed quickly. Renewable energy sources such as solar, wind, geothermal and Bioenergy are available around the world. Multiple studies have shown that renewable energy has the technical potential to meet the vast majority of our energy needs. Renewable technologies can be deployed quickly, are increasingly cost-effective, and create jobs while reducing
