Test your knowledge with our quiz:
Which of these countries have vowed to use only 100% renewable energy by 2050?
At the United Nations Climate Change Conference (2016) in Marrakesh, Morocco, 48 countries, who are members of the Climate Vulnerable Forum, pledged to use only renewable energy by 2050. These countries are often those who are and will be affected by climate change the most. Some of the countries who committed include Afghanistan, Bangladesh, Kenya, Guatemala and Vietnam. As of 2020, more than 110 countries have committed to carbon neutrality by 2050.
Which country has not run completely on renewable energy for a period of time?
While some places in the United States have run on 100% renewable energy, such as Burlington, Vermont, the entirety of the country has not. Some countries that have run completely on renewable energy for a period of time include Denmark, who ran entirely on wind for a day; Portugal, who ran on wind, solar and hydropower for four days; and Costa Rica, who was powered by renewable energy for more than 100 days.
True or False: Across the globe, the coal industry is declining, while renewable energy industries are on the rise.
Global coal demand has decreased in 2019 and 2020, following two years of growth in coal demand. Although demand is expected to rise in 2021, renewable energy is projected to surpass coal as the largest global electricity source in 2025. In 2019, renewable energy comprised around 11% of global primary energy.
Which of the following is not considered to be a source of renewable energy?
The correct answer is natural gas.
According to the US Energy Information Administration, renewable energy sources, which re-generate, consist of biomass, hydropower, geothermal, wind and solar.
Which of the following are negative impacts of burning fossil fuels?
Fossil fuels and the fossil fuel industry have many negative impacts. Some are direct and easily visible, such as pollution and land degradation. Others may not be so obvious. For example, fossil fuels can put human health at risk. Coal miners may develop black lung disease, or communities near transportation routes may be exposed to coal dust. Local communities may be at risk in terms of health, but extraction techniques such as surface mining can also increase the amount of mudslides, landslides and flash floods.
True or False: Using more renewable energy sources would have a larger overall land impact than non-renewable energy.
Renewable energy sources have a smaller overall land impact than non-renewable energy. Land used for non-renewables, such as nuclear and coal, can be used only once, while land for renewables can be used multiple times and for different purposes.
In 2019, about how much of the United States’ energy consumption derived from renewable sources?
In 2019, 11% of total energy consumption in the United States came from renewable sources. The United States also generated about 17% of its electricity from renewable sources.
Which is one of the fastest growing renewable energy sectors in the world?
Solar energy is one of the fastest growing renewable energy sectors in the world. In 2018, solar energy produced just over 2 percent of the world’s electricity. Overall, renewable energy used for electricity has grown by around 7% in 2020.
According to scientists, about how many countries could run entirely on wind, solar and water power by 2050?
According to a roadmap created by scientists, by 2050, nearly 140 countries could run on energy created solely from wind, solar and water power. They represent more than 70% of the world’s countries. Doing so could help avoid some of the consequences of climate change, while also preventing millions of premature deaths each year and generating jobs.
Which US state has proposed to commit to 100% renewable energy electricity?
Eight US states have committed to 100% renewable energy electricity: Hawaii, California, Maine, Washington, Nevada, New Mexico, Virginia and New York.
