Imagine what the world would look like if industrialized countries had skipped the age of fossil fuels and gone directly to solar power.
Our infrastructure, way of life, and environment would be radically different.

Of the more than 51 million people living in Tanzania, 70% don't have electricity at all, either because they’re not connected to the energy grid, or, if they are, they still don't have electricity due to poor connections and frequent outages.
Mtemahanji knows firsthand what it's like to live without electricity.
He grew up studying by kerosene light and going to bed at 8 p.m. (the sun goes down in Tanzania at 6 pm).
"I understand very well the discomfort that people who have no electricity have," he told Upworthy via email. "I was born at night in a clinic without electricity, and so I was born with the light of the moon. My mom always told me that she had to wait [until] the next day to see me, she knew I was born healthy because I weighed nearly 4kg, but she could only see me the next morning. ... I was born and I lived without electricity and I know what it means, for this I decided to use all my knowledge to light up the lives of all those who do not have electricity."
In 2003, Mtemahanji moved to Italy with his mother and became a technician in renewable energy before going to work in Switzerland. By 2014, he’d saved up enough to return to Tanzania, where he started a business with a friend, Manuel Rolando.
The business they started is called SunSweet Solar Limited, and it has the potential to solve three major problems at the same time.
Solar power seemed to Mtemahanji and Rolando like the perfect way to resolve a few different problems simultaneously — (1) bringing electricity to people who needed it, (2) in areas that were mostly poor, and (3) without contributing to climate change.
SunSweet Solar designs, plans, and constructs solar photovoltaic systems, water pumping systems, street light systems, and off-grid lighting.

SunSweet Solar's first contract involved installing a solar power plant at a secondary school that could run 236 lights, dozens of computers, and fans.
The project was challenging, but it was also a success, and Mtemahanji was curious to see how having electricity affected the students.
He wasn't disappointed; he says that since SunSweet Solar's installation last year, national exam performance at Benignis Girls Secondary School increased from 81% to 94%.
Mtemahanji attributes at least some of that success to the introduction of electricity.
"This result shows that studying in a serene environment where electricity is always present, can help a lot to improve the quality of education."
In addition to big projects like the Benignis school, the company sells solar kits and installs larger scale solar systems.
The plan originally was to sell solar kits capable of powering a few lightbulbs and charging a phone to individual households, but SweetSun Solar has since changed its model: nNow they install single solar systems that can satisfy the energy demands of a whole village.

SunSweet Solar customers pay for the solar setup in installments through their phones, and it costs them about $0.13 a day. The government of the village earns 5% of the revenue to assist in the development of the village.

In October 2015, SunSweet Solar was selected as one of the 12 best companies led by young Africans by the Anzisha Prize, an award celebrating young African entrepreneurs.
Since the award, sales have skyrocketed, and SunSweet Solar now faces a new challenge: how to keep up with demand. The company gets requests from about four villages every month, each village with an average of 30 customers/houses. Mtemahanji and Rolando are currently looking for investors so that they can scale up their business.
Mtemahanji says it can be discouraging because it seems like many investors want to work with Western and Asian companies operating in Africa rather than directly with Africans.
"We must be content with the funds that we can have through the seed and prizes. But many of these funds help to support the company, not to scale up. I am confident, however, that this situation will change soon as possible, and we are ready for that moment."

You just know there's a person named Whiskey out there getting a kick out of this. 


An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
