Renewable energy is gaining popularity worldwide due to the increasing price of fossil fuels as well as the risk of climate change. At present, there have also been some developments in this area like enhancement in efficiency and reducing prices. All of these developments have enhanced the demand for cleaner and more sustainable techniques of electrical power. Lets talk about it now- Renewable energy is energy produced from sources that do not deplete or can be replenished within a human’s life time. The most common examples include wind, solar, geothermal, biomass. This is in contrast to non-renewable sources such as fossil fuels . Also, most renewable energy is derived directly or indirectly from the sun. Sunlight can be captured directly using solar technologies. The sun's heat drives winds , whose energy is captured with turbines. Plants also rely on the sun to grow and their stored energy can be utilized for bioenergy.Not all renewable energy sources rely on the sun. For example, geothermal energy utilizes the Earth’s internal heat, tidal energy relies on the gravitational pull of the moon, and hydropower relies on the flow of water. Although , Renewable energy accounts for 13.5% of the world’s total energy supply, and 22% of the world's electricity . Renewable energy systems are a major topic when discussing the globe's energy future for two main reason . First one is Renewable energy systems provide energy from sources that will never deplete and another one is renewable energy systems produce less greenhouse gas emissions than fossil fuel energy systems. Last but not the least , while renewable energy systems are better for the environment and produce less emissions than conventional energy sources, many of these sources still face difficulties in being deployed at a large scale including, but not limited to, technological barriers, high start-up capital costs, and intermittency challenges. |

Hi rideeta
Very well organized report about renewable energy. You described the true source of those energy in logical way, which is the sun.
Transition to renewable energy is a inevitable movement until the air of the planet become perfectly clean. With technological research, benefits of the renewable energy should be expanded, while the limitations of them are to be overcome. I certainly believe that can be accomplished sooner or later.
Thank you for the great report.
Keep up the good work.

Hey Rideeta!
This is your mentor Lisa.
I think you have done some great research on the topic. It is true that there are both goods and bads on renewable energy. We do need to solve the high-cost problem and also the technological limits as well. However, if we do succeed in overcoming these barriers we will be able to enjoy the harm free energy for our life.
Yet, as I have commented on the article, there are some clear negatives regarding renewable energy other than the problems that you have mentioned. There are trade-offs for developing these energy sources. You should check them out!
Thanks for the article:)
