The United States has experienced a substantial increase in energy consumption over time, driven by factors like population growth and technological advancements. The transition from forests to coal, followed by oil and natural gas, has shaped the country's energy sources. However, fossil fuels still dominate energy use, highlighting the need for a rapid shift towards renewable and low-carbon alternatives.

This is a brief introduction for College-Level ESL students on how to use sources in their writing.

This activity helps students evaluate their own authority on a particular subject so that they can begin to understand how authority is created and effectively evaluate the authority of other sources they encounter. Additional evaluation criteria is also introduced.

As of January 2023, 575 utility-scale biopower plants were operational globally, with a total capacity of over 29,000 MW, less than 0.5% of worldwide power generation. An additional 6,000 MW are under construction. China is believed to significantly underreport its true biopower capacity, perhaps as high as 22,000 MW, primarily from agricultural residues and waste-to-energy facilities. Brazil, another major player, relies largely on sugarcane byproducts.

Biopower is electricity generated from renewable organic materials, such as plants and animals. Different countries rely on various biomass sources, including sugarcane, trees, and municipal waste, to produce biopower. However, the impact of biopower on climate change is complex. Despite being initially perceived as carbon neutral, the use of fossil fuels in bioenergy systems and the land requirements for biomass production can have significant environmental consequences.

Hydropower's history traces back to 1882 when the first facility began supplying electricity in Wisconsin. Its adoption surged across North America, Europe, and beyond, with China notably driving expansion in recent decades. Hydropower now contributes 17% of global electricity, surpassing nuclear, wind, solar, bioenergy, and geothermal combined.

Nuclear power plant construction has shifted to countries like China, India, Russia, and South Korea. Around 64 GW of new nuclear capacity is currently under construction, with China leading the way. An additional 177 GW has been announced globally. Some countries see nuclear power as a low-carbon option to meet climate goals. Factors such as economics and geopolitical considerations will determine how much new nuclear capacity actually gets built.

Global natural gas consumption has risen 70% from 2000 to 2022, fueled by economic growth and coal-to-gas transition. Hydraulic fracturing in the US has played a major role. Liquefied natural gas (LNG) enables long-distance shipping, but presents climate and energy justice challenges.

A major challenge when writing with sources as a graduate student is learning just how to integrate the material you read into your writing in a way that:

•Shows you understand the material•
Allows room for your own ideas•
Distinguishes your ideas from your sources’ ideas

Coal has played a pivotal role in the United States' industrial history, fueling steel production, electricity generation, and economic growth in the early 20th century. However, this legacy also comes with significant environmental and health issues, including miner health problems, landscape degradation, abandoned mines, and pollution.
