What is a solar eclipse and why are they only visible in some parts of the world? In this video segment adapted from NASA, astronomer Susan Stolovy uses animations to provide an answer to these questions.
In this activity, students learn how engineers use solar energy to heat …
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.

Working as if they were engineers, students design and construct model solar sails made of aluminum foil to move cardboard tube satellites through “space” on a string. Working in teams, they follow the engineering design thinking steps—empathize, define, ideate, prototype, test, redesign—to design and test small-scale solar sails for satellites and space probes. During the process, learn about Newton’s laws of motion and the transfer of energy from wave energy to mechanical energy. A student activity worksheet is provided.

Students explore energy efficiency, focusing on renewable energy, by designing and building flat-plate solar water heaters. They apply their understanding of the three forms of heat transfer (conduction, convection and radiation), as well as how they relate to energy efficiency. They calculate the efficiency of the solar water heaters during initial and final tests and compare the efficiencies to those of models currently sold on the market (requiring some additional investigation by students). After comparing efficiencies, students explain how they would further improve their devices. Students learn about the trade-offs between efficiency and cost by calculating the total cost of their devices and evaluating cost per percent efficiency and per degree change of the water.

Sixth grade students at Eckstein Middle School use their understanding of electricity to explore electrical current in a circuit with photovoltaic cells.Using a lamp to model the sun, students work in teams and connect different power sources in series and parallel circuits to determine the effects on light bulbs or small motors. Discussion between students about the differences in voltage and the flow of electrons from negative to positive terminals provide opportunities for students to explain their learning and for the teacher to assess their understanding.Learning is extended beyond the experiment as students use photovoltaic cells to power equipment and offset electrical load in the classroom.

Solar thermal energy is a vast renewable energy resource that has been harvested by human civilizations for centuries. Now as energy conversion technologies quickly develop, we look at solar thermal energy as a significant contributor to the future world's energy profile. Solar heat, when properly collected and stored, can provide cost-effective benefits to a wide array of industrial and residential applications. In EME 811, Solar Thermal Energy for Utilities and Industry, we talk about both the main principles of solar thermal energy conversion and some implementation scenarios, such as utilization of solar heat in buildings, solar cooling, solar desalination, solar drying, and chemical processing.

Visualizing Energy is an open access, interdisciplinary science communication project that aims to increase actionable knowledge about a sustainable and just energy transition. It uses engaging visualizations coupled with accessible data stories to communicate in clear, concise, jargon-free language. It is highly interdisciplinary and uses energy as an organizing principle to reveal logical connections across disciplines. Visualizing Energy knits data analysis, visualizations, and the written word into stories that promote critical thinking and communication. Its initial focus is on three interconnected areas: the connection between energy and human well-being; the history of energy transitions; and equity issues surrounding energy transitions (energy justice, energy burden, energy poverty, energy insecurity).
The project co-leaders are Cutler J. Cleveland, Professor of Earth and Environment, and Heather Clifford, data scientist in the Boston University Institute for Global Sustainability.

In 2022, the United States saw a significant rise in solar power generation, with 5730 utility-scale solar PV plants and 13 solar thermal plants producing 146 terawatt-hours (TWh) of electricity, equal to 3.4% of total utility-scale generation. This growth traces back to the 2000s, marked by falling solar system costs, enhanced efficiency, and government incentives like the American Recovery and Reinvestment Act of 2009.
