What’s the oldest form of renewable energy?
Water power dates all the way back to over 2,000 years ago when the Ancient Greeks used the power of rivers and streams to crush grain and make bread. However, hydropower- or using water to generate electricity- was invented just over 100 years ago. Harnessing the power of water has transformed from large, wooden wheels to devices called turbines that spin and create electricity.
Which renewable energy source is most prevalent across the globe?
In 2020, renewable energy sources made up over 28% of the world’s electricity, and that number is rising every year. Around 60% of renewable electricity worldwide comes from hydropower. Here is a great source to learn more about electricity and how it’s generated across the globe.
Which of the following statements is true about the land use for onshore wind farms?
The land between wind turbines can be used for other purposes, such as agriculture. Projects such as the Roscoe Wind Farm in Texas utilize their land to harvest wind and crops simultaneously, allowing for two sources of income. Other, more densely packed wind farms cannot support agriculture.
True or False: Wind energy exceeded coal-generated electricity in both March and April 2024.
Wind generated electricity exceeded the coal-generated electricity in both March and April of 2024. This is a new record, as wind has not exceeded coal for more than two consecutive months. The last time wind exceeded coal was April 2023.
What is a potential negative impact of wind turbines on nearby communities?
While there are many benefits to wind-powered electricity, there are still many concerns about its use. Some trepidations stem from turbines’ ability to function in icy weather conditions and their destructive potential if a blade were to come loose. However, there are many strategies implemented to minimize these risks.
When was geothermal energy first used?
Geothermal energy has been used since prehistoric times for cooking, cleaning, and bathing by the Greeks, Romans and other ancient civilizations. Hot water was commonly thought to have healing properties: the Japanese have used thermal waters to purify since the 8th century A.D. Geothermal energy was first utilized industrially in 1918.
What are the main benefits of using geothermal energy as a source of power?
It is almost inexhaustible, clean, and independent of weather conditions. The inexhaustibility of geothermal energy results from its heat source: the core of the earth, a resource that won’t easily be used up. Geothermal plants almost exclusively release excess steam, a byproduct more harmless than most other forms of energy. And because of their locations close to the core of the earth, geothermal power plants will not be affected by fluctuating weather conditions.
What is a significant environmental concern associated with geothermal energy extraction?
Drilling can disrupt habitats and lead to air and water pollution. Fluid withdrawal and surface disturbance can release harmful and toxic chemicals, and have the potential to kill surrounding fish and wildlife if concentrated. Hazardous waste disposal is another concern when considering the efficacy of geothermal energy extraction.
True or false, solar energy is becoming more and more expensive.
The cost of solar electricity is set to decline by 60% by the year 2050. Simultaneously, solar energy’s role in global electricity generation is set to increase and surpass 50% by that same year.
Which of the following are benefits of installing residential solar energy systems?
Here is a great source outlining the benefits of installing solar at your home. As solar panel technology develops and becomes more common, energy generation will become more efficient, cheaper, and less impactful on the environment.
