The Sahara Desert can transform Africa into a solar energy superpower. Concentrated solar power (CSP) and photovoltaic power (PV) hold the answers to the energy revolution in the region.

Big picture

  • If all sunlight received by Northern Africa converted into solar energy, it could power all of Europe more than 1000 times over.
  • Concentrated solar power (CSP) technology can use lenses and mirrors to store large amounts of solar heat. 
  • Tunisian transcontinental transmission of photovoltaic power (PV) and CSP prove this concept.
  • PV is more reliable for decentralized plants to power rural regions in Africa.

Between the lines

  • To better understand how a CSP plant works, check out the Ivanpah Solar Electric Generating System in California’s Mojave Desert.
  • Desert solar panels can improve climate conditions in the region.
    • Compared to sand, panels reflect lower amounts of heat to space.
    • The result: surface heating in the desert and cloud formation.
    • Changing the desert’s heat budget may increase precipitation levels. 

Questions to consider

  • What companies would fund the project? 
  • Who would benefit from affordable solar electricity? 
  • How can you export energy to nations inside and outside of Africa?

Why it matters

  • CSP can release energy overnight, creating a 24-hour source of energy.
  • CSP has a high initial set-up cost but has long-term advantages over traditional forms of energy generation such as hydroelectricity.

Bottom line The developing world has a unique opportunity to learn harsh lessons from 20th century economic development principles. Using natural phenomena like the Sahara Desert or the Congo River, Africa can become the solar energy superpower of the future.

Hot take music festivals need sustainability now more than ever.

What’s the matter The music industry is an integral part of society, but it has some catching up to do in the world of sustainability. With constant traveling, waste production and energy demands, tours and festivals carry a heavy environmental impact.

By the numbers

  • A UK study found that in 2015, five artists collectively generated 19,314 kilograms of CO2 emissions between April and September (the equivalent of 1 million people’s CO2 emission per year)
  • Tours can go through 18,720 plastic bottles a year

Bottom line While touring and festivals may be environmentally harmful now, there are many potential solutions for eliminating single-use plastics, utilizing biodiesel in transportation, recycling batteries, sourcing merchandise made from organic materials, promoting carpooling to the event, and educating fans.

The global spread of the coronavirus has caused layoff after layoff in the United States, forcing over 40 million Americans to file for unemployment in less than three months. How can America put its citizens back to work while fighting climate change?

What to know

  • FDR kickstarted the economy in the Great Depression by creating the Civilian Conservation Corps to restore America’s infrastructure while employing jobless workers – similar programs could help unemployed workers during COVID-19
  • Other countries are already doing it – Pakistan has employed 63,000 people in its 10 Billion Tree Tsunami Programme
  • Governments control more than 70% of energy investments globally, so they can steer recovery in a positive direction for the climate and their people
  • With an additional $15 trillion in a global COVID-19 recovery plan, we can increase our global GDP by 2.4% and add tens of millions of jobs in energy and infrastructure

Bottom line

  • Implementing a green stimulus is necessary to effectively combat climate change as we emerge from the grips of COVID-19
  • Many communities disproportionately affected by the coronavirus are also disproportionately affected by climate change, so we must target a dualistic recovery

What’s the sitch? For all the innovations we have today, access to quality food is still a critical issue across the globe. Food disparity is driven by a number of factors, such as income inequality and local production levels.

Big picture The barriers that prevent many people from eating healthier are interconnected with race, inequality, and systemic biases embedded in our society. Race, education, careers, income, and housing all play a role in determining food access.

Why it matters Overcoming system inefficiencies like excessive subsidies for meat production helps to lower barriers to healthier foods but it will take a national and global effort to completely eradicate systemic inequalities.

Big picture In the age of corporate social justice, sustainability risk management can help firms make better choices for the planet while staying competitive.

Why it matters

  1. Identify the effects of sustainability issues on internal and external stakeholder value.
  2. Actively include sustainability in objective setting and cascading objectives across the levels of the organizational hierarchy.
  3. Develop concrete support for identifying, assessing, and managing economic sustainability risks.

Bottom line Sustainable risk management is the most effective and realistic strategy for creating a sustainable economy, as it allows companies to achieve the best of both worlds: financial success and climate risk mitigation.

Welcome to Earth Day, 1990s edition. The U.S. population was 250 million. The Berlin Wall was collapsing. Fresh Prince, Home Improvement and Friends filled our TV screens. Gameboys were the ‘next big thing’. Yes, frosted tips, flat tops and boy bands everywhere. These are the biggest events of the environmental movement of the 1990's that dominated the decade.

This is the 1970s: Watergate, Star Wars, heavyweight boxing, leisure suits, big hair, rock and roll. Add environmentalism to the list. Richard Nixon is most well known for the Watergate scandal, but he was also one of America’s most environmentally influential presidents, and some of his accomplishments are noted below. The first half of the 1970s was marked by governmental actions that had significant impacts both in America and abroad. The second half of the decade included a series of environmental disasters that raised widespread consciousness into the importance of protecting our planet.
