Biopower is the production of electricity from biomass-derived fuels, with significant growth in Brazil due to sugarcane-based ethanol byproducts, while in certain regions like the United States, Germany, and the United Kingdom, waste-to-energy facilities are used due to land constraints and landfill opposition.

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.

Geothermal power has a long history, with Native Americans and ancient civilizations like the Greeks and Romans utilizing its benefits. Today, countries such as the United States, Indonesia, the Philippines, Turkey, and New Zealand are leading the way in building new geothermal power projects to harness clean and sustainable energy from the Earth's heat.

ountries worldwide, including Germany, Spain, China, the United States, and others, are rapidly expanding their solar power infrastructure. China has been a particularly prominent player, contributing nearly one-third of new capacity additions.

Wind power in the United States has seen significant growth. California led the way in the 1980s, and wind energy quickly spread across the Wind Belt, including states like Texas. Favorable policies and declining costs contributed to the expansion. Wind now accounts for about 9% of national electricity generation, with Texas having 37 GW of installed wind capacity, ranking third globally.

The wind energy industry started in the 1980s in Southern California and several European countries. Today, the United States, Europe, and countries like India, Australia, Japan, Canada, China, and Brazil lead in new wind power capacity. Currently, wind power generates around 7% of global electricity, with onshore systems dominating but offshore capacity expected to grow in the future.

In this problem-based learning module, students will investigate the following question: Does the state of Ohio suffer from “Brain Drain?”If so why is this, where are people going, & what can be done to stop it?If not, what is keeping/bringing people here?After researching and learning about some of the push-pull factors that drove 19th century European immigration to the United States, student groups will be formed in order research, create, and share their findings to determine whether or not Ohio is a “push” or “pull” state.After the launch activity, students will spend the first two days gaining background knowledge on the historical components and content related to the topic.  Beginning on Day 4, students will be grouped into teams to begin research and development of the “BIG IDEA” question of: Does the state of Ohio suffer from “Brain Drain?”If so why is this, where are people going, & what can be done to stop it?If not, what is keeping/bringing people here?Once the groups have determined their position on the problem, they will begin researching information to be able to share out their findings.The final products will be presented to an authentic audience consisting of District Administration (i.e., media relations), Local Administration (elected officials), and possibly, local Chamber of Commerce members

This course surveys the increasing interaction between communities, as the barrier of distance succumbed to both curiosity and new transport technologies. It explores Western Europe and the United States’ rise to world dominance, as well as the great divergence in material, political, and technological development between Western Europe and East Asia post–1750, and its impact on the rest of the world. It examines a series of evolving relationships, including human beings and their physical environment; religious and political systems; and sub-groups within communities, sorted by race, class, and gender. It introduces historical and other interpretive methodologies using both primary and secondary source materials.

This lesson is based on Pearson's My World History and Geography adopted for instruction in TN for the 6th grade World History class.

This is a remixed version of World History: Culture, States, and Societies to 1500 by Berger, et al. It's a textbook suitable for the World History survey. I have reorganized the text in order to provide a more globally integrated narrative. Each chapter invites students to compare and contrast developments across regions during a period of time.

This version of the book retains the text of the original but with updated references to chapters. I verified and, if necessary, updated links to online resources. In cases where the exact illustration used in the original version was not available, I have substituted equivalent ones. I also created and edited segues and other “connective tissue” as well to (hopefully) ensure that this version of the book reads as smoothly as the original.

Additional changes include:

More concise lists of “key terms” in each chapter
Expanded coverage of the Persian Empire
Expanded coverage of the end of the Yuan Dynasty
Added brief overview of the early Ming Dynasty including the voyages of Zheng He

The world in 1750 was the product of a long and complex global history. Humans lived across most of the habitable world. In some ways, they did things the same as their ancestors—most people farmed, they moved around only a little, their states were some kind of monarchy, and religion was the most present large-scale community in their lives. Things were changing, but nobody was quite sure how they were going to change. This was signified by an encounter between the Qianlong Emperor and Lord Macartney.
