GivePower

GivePower is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand GivePower rather than just read about it. In short: GivePower is a 501(c)(3) non-profit organization that develops clean water and energy systems in communities across the world. GivePower has installed 2,650 solar power installations in villages across 17 countries and in underdeveloped areas of the United States.

Key takeaways

GivePower belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GivePower to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GivePower from memory before moving on to harder problems.

Reference excerpt

GivePower is a 501(c)(3) non-profit organization that develops clean water and energy systems in communities across the world. GivePower has installed 2,650 solar power installations in villages across 17 countries and in underdeveloped areas of the United States.

History GivePower was co-founded in 2013 in California by Hayes Barnard and Lyndon Rive as the non-profit branch of SolarCity. After SolarCity merged with Tesla in 2016, GivePower was spun off into an independent organization just before the merger was completed. The president of GivePower is Hayes Barnard. In 2014, the organization's first focus was to provide one school with solar-powered lighting for every megawatt of solar system installed by SolarCity that year. In 2021, GivePower was listed as a finalist in Fast Company's 2021 World Changing Ideas Awards.

Projects In 2016, GivePower began developing solar powered desalination technology that could be exported to developing regions. The desalination systems are contained within 20-foot shipping containers and can desalinate up to 75,000 gallons of seawater and/or brackish water into potable water per day. In 2018, GivePower installed its first desalination plant in Kiunga, Kenya, which is also solar powered. The project cost $500,000 and took one month to construct. As of 2019, the Kiunga plant could produce enough drinking water for up to 50,000 people per day and requires minimal maintenance. As of 2018, GivePower had installed 2650 solar power installations in villages through seventeen countries for institutions like primary schools and medical clinics. They have also developed solar installations in underdeveloped areas of the United States, including the Standing Rock Sioux Reservation. Once installations are completed, GivePower transfers the maintenance and running of them to local communities. In 2019, GivePower built a 300 kilowatt solar farm on the Standing Rock Sioux Reservation which became the largest solar installation in North Dakota. The project was a partnership between Empowered by Light and GivePower, and the total cost was $470,000. The maintenance of the solar farm also created jobs for the Sioux Nation Tribe. The same year, the organization partnered with World Hope International to build a solar-powered desalination center in Haiti. The water plant was fully operational and self-sufficient by 2020.

Worked examples

Example 1 — a first encounter with GivePower

Start with the simplest possible case. Write down what GivePower claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to GivePower before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about GivePower ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of GivePower

In research: GivePower appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses GivePower in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: GivePower is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2013 establishments in California, Charities based in California, Solar power, so understanding it makes those chapters shorter.
In everyday life: Look for GivePower outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is GivePower in simple terms?

Why does GivePower matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GivePower?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
