Do you find food labels confusing and hard to understand? Besides the required FDA label, manufacturers use various seals and badges with claims about what the food does or does not contain.
We need food to survive, and in the U.S., we have a lot of choices when it comes to the food we put in our bodies. However, not all the food we ingest is good for us.
Statistics show that more than 34% of adults over the age of 20 are overweight, and almost 34% of adults are obese. Therefore, we need to be aware of what’s in our food before we eat it.
The regulations behind food labels can be complex and confusing. Food manufacturers use this confusion and complexity to their advantage. Some try to sell you products that claim to be healthy but really aren’t. Knowing the ingredients in your food and how much a serving size is can help you maintain a healthier diet.

Perovskite crystal, CaTiO3 (Calcium, Titanium, Oxygen)
Researchers in alternative energy have been excited about perovskite solar technology for years now. They have also struggled to overcome serious challenges
A perovskite is a mineral crystal comprising calcium, titanium, and oxygen. Other minerals, technically perovskite structures, have the same structure, but different elements.
The distinction between perovskite and perovskite structure matters only in geology. The solar industry uses the terms interchangeably.
Certain perovskites have several properties that make them useful in solar applications, including superconductivity and catalytic properties.
They are incorporated into organic photovoltaic thin films, an aspect of nanotechnology. Continue reading →
Wattle Point wind farm, South Australia
Wind power has been part of the story of two different storms.
Critics of renewable energy blamed South Australia’s high penetration of wind power for a state-wide blackout in the wake of a spate of tornados. Partisan bickering about the feasibility of wind power started immediately and continues.
On the other hand, Hurricane Harvey slammed into a part of Texas with several wind farms. One continued to operate normally throughout the storm. The rest were back online within days. No one blamed wind energy for making the crisis worse.
What can we learn from the contrast? Continue reading →
Vinegar belongs in every household cleaning arsenal, but you need to beware of vinegar cleaning myths.
It’s not really a cleaner or a disinfectant. Combining it with other common natural cleaners can render it useless.
In fact, “natural cleaners” is a near-mythical phrase. No definition of “natural” has been made official. It can mean whatever the person using wants it to mean.
I mean those old-fashioned and versatile cleaners like borax, baking soda, or salt. The kind of cleaners that make such a great alternative to the heavily advertised products in the cleaning aisle. Continue reading →
At the very least, living a sustainable life means simplicity and frugality.
We can’t go out and buy all the stuff advertisers try to cram down our throats.
We don’t need the most powerful car on the block or the fanciest home entertainment center.
And we can’t afford to live paycheck to paycheck and max out on credit cards to get all of it.
The broader concept of sustainability includes attention to the environment. As Thoreau asked, “What’s the use of a fine house if you haven’t got a tolerable planet to put it on?” Continue reading →
Advice on how to stop wasting water often includes various ways of reusing water.
Watering houseplants with cooking water, for example. It also includes how to maintain your home’s plumbing.
In this post, I want to focus on how letting water run unnecessarily wastes water. Continue reading →
