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.
How many global clean energy jobs were reported in 2023?
According to the International Renewable Energy Agency (IRENA), there were 16.2 million global renewable energy jobs in 2023, an increase from 13.7 million jobs in 2022. China leads the industry with 7.4 million jobs, 45% of total global renewable energy jobs, followed by the European Union, Brazil, and the United States. Solar photovoltaic had a total of 7.1 million jobs, hydropower 2.3 million, biofuel 2.8 million, and wind 1.5 million.
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.
True or False: Renewable energies anticipate to surpass coal as the largest source of global electricity generation by early 2025.
Renewable energy trends following the conclusion of COP28 conference in Dubai this past December report a global shift towards renewable energy development. The report highlights that the global renewable energy capacity is expected to grow to 7,300 GW during the 2023-2028 period covered by the data collection. Solar PV and wind energies account for 95% of this expansion.
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.
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 sectors within renewable energy companies will drive job growth?
The renewable energy market is expanding at a fast rate, with solar photovoltaic leading this industry with 4.3 million jobs currently. Although many different sectors and skill sets can influence the renewable energy job market, manufacturing, construction and installation, and operations and maintenance are the three key stand outs.
How much money has been invested in clean energy worldwide?
According to the International Energy Agency (IEA), for the first time in history, global energy investment in clean energy reached 2 trillion USD. Meanwhile, 1.16 billion USD was spent on investing in the fossil fuel industry. It is estimated that solar photovoltaic (PV) technology exceeded 500 billion USD in 2024.
How much money can be saved globally by 2050 through phasing out fossil fuels and implementing renewable energies?
According to a recent study done by the University of Oxford, the costs of renewables have been consistently declining for decades. As we continue to transition to renewables, they will become cheaper at an even faster rate. Researchers modeled a scenario where the world used 55% more energy than it does today. In that scenario, a shift to renewable technologies would save approximately $12 trillion globally.
How much money can a household save annually by switching to renewable energy?
A report done by Rhodium Group analyzed the cost effectiveness of investing in clean electricity, electrification, and energy efficiency. It was found that in the United States, the average household would be able to save $500 annually with the implementation of clean energies.
