Renewable energy development has become an increasingly important issue in recent years due to the negative impacts of traditional energy sources on the environment. As the world seeks to address the threat of climate change, renewable energy has emerged as a key solution to reducing carbon emissions and promoting sustainable development. In this article, we will explore the current state of renewable energy development and its potential for the future. Renewable energy refers to energy that is generated from natural resources that are replenished over time, such as sunlight, wind, rain, and geothermal heat. Unlike fossil fuels, which are finite and non-renewable, renewable energy sources offer a sustainable and clean alternative. Renewable energy is also becoming more cost-competitive with traditional sources of energy, making it an attractive option for countries around the world. The global renewable energy market has been growing rapidly in recent years, with investments in renewable energy exceeding those in traditional fossil fuels for the first time in 2015 (International Energy Agency, 2016). According to the Renewable Energy Policy Network for the 21st Century (REN21), renewable energy accounted for almost 72% of all new power capacity added globally in 2019, with solar and wind power accounting for over 90% of this growth (REN21, 2020). One of the most promising areas of renewable energy development is in the field of solar energy. Solar energy is generated by capturing the energy from the sun and converting it into electricity using photovoltaic (PV) cells. The cost of solar energy has fallen significantly in recent years, making it increasingly competitive with traditional fossil fuels. In fact, the International Energy Agency (IEA) predicts that solar energy will be the cheapest source of electricity in many parts of the world within the next decade (IEA, 2020). Another area of renewable energy development with significant potential is wind power. Wind power involves harnessing the energy of the wind using wind turbines to generate electricity. Like solar energy, the cost of wind power has been falling rapidly, and it is now often cheaper than traditional fossil fuels in many parts of the world (IRENA, 2020). Geothermal energy is another renewable energy source with significant potential. Geothermal energy is generated by tapping into the heat energy produced by the earth's core. While geothermal energy is not yet as widely used as solar or wind power, it has the advantage of being a stable source of renewable energy that can provide baseload power (IRENA, 2019). Despite the significant growth in renewable energy development in recent years, there are still many challenges that need to be addressed. One of the biggest challenges is the intermittency of many renewable energy sources. Solar and wind power, for example, are only generated when the sun is shining or the wind is blowing. This makes it difficult to rely solely on renewable energy sources to provide baseload power, which is necessary to meet the energy demands of society. To address this challenge, there has been increasing investment in energy storage technologies, such as batteries, to store excess renewable energy for use when it is needed. There has also been increasing interest in developing technologies such as hydrogen fuel cells, which can convert excess renewable energy into hydrogen for use in fuel cells to generate electricity. In conclusion, renewable energy development has the potential to revolutionize the global energy landscape, providing a sustainable and clean alternative to traditional fossil fuels. Solar and wind power are the fastest growing sources of renewable energy, but there are also significant opportunities in geothermal, hydropower, and biomass energy. While there are still challenges to be overcome, such as intermittency and energy storage, the future of renewable energy looks bright, and it is likely to play an increasingly important role in meeting the world's energy needs in the years to come.

Hello Kenya! This is your mentor Yewon.
Before I start, I apologize for the late comment.
The article discusses the growing significance of renewable energy development as a response to environmental concerns and climate change. It highlights the increasing competitiveness of renewable sources like solar, wind, and geothermal energy, with global investments surpassing fossil fuels in recent years.
Thank you for your meaningful report! Great job!

Hello Kenya! This is your mentor James.
First of all, terribly sorry for the late comment!
I see that your topic of this report is renewable energy development! As you've mentioned, solar, wind, and geothermal power are major fields of research in terms of renewable energy. I'm certainly glad to hear that 72% of the newly added energy production in 2019 is renewable! One day, I believe that percentage of renewable energy may be applied to the actual global energy production.
Thanks for writing such a meaningful report! Let's keep up the good work.
