Individual Action on Climate Change
Renewable energy sources are those that can be replenished naturally within a short period of time. They are considered to be a crucial part of the solution to climate change as they displace conventional sources of energy that produce large amounts of greenhouse gases. Examples of renewable energy sources include:
Solar power is the most abundant and widely available source of renewable energy. It is harnessed by using photovoltaic cells to convert sunlight into electricity.
Wind power is generated by harnessing the kinetic energy of wind using wind turbines.
Hydro power is generated by harnessing the energy of flowing water in rivers and dams.
Geothermal power is generated from the heat of the earth's core.
Biomass energy is generated from organic matter such as wood, crops, and waste.
Renewable energy sources are becoming increasingly competitive with conventional energy sources as the cost of technology decreases and the efficiency of renewable energy systems increases. In many parts of the world, renewable energy sources are now cost-competitive with fossil fuels. In addition to being better for the environment, renewable energy sources can also provide energy security and increased economic opportunities.
However, there are still challenges to overcome in the adoption of renewable energy sources. One of the biggest challenges is the intermittency of renewable energy sources such as wind and solar. This means that energy is not always available when it is needed, as it depends on factors such as the weather. There are also challenges in integrating renewable energy sources into existing power grids, as they may require different infrastructure and management systems.
