In this high-tech age, our gadgets can be essential lifelines. Smartphones, tablets, laptops and other devices are what help us connect with colleagues, avoid boredom and find our way from Point A to Point B. They can seem almost magic, but there’s one great equalizer that limits them all: battery life.

If you depend on your devices, keeping them charged is critical. But life doesn’t always work that way; you often can’t stay tethered to an outlet for an hour or more, and sometimes an outlet just isn’t there when you need it. And that’s where portable chargers come in.

Power to Go

A portable charger is like a second battery for your device, and some models hold enough juice to charge your devices a few times over. Charge your trusty portable charger at the same time you charge your phone, and you can walk around with double, triple or even quadruple the battery life you’re accustomed to.

The portable charger market is getting bigger all the time, so choosing a model can feel a little overwhelming. But that also means that if you know what factors to consider, you can find the perfect charger for your needs.

When shopping for a portable charger, consider these key attributes:

Size and weight: The smallest portable chargers are about the size of a tube of lipstick, while others may be as big as your hand and nearly an inch thick. Similarly, some are virtually weightless, compared to larger chargers that are even heavier than they look. You might want one of each -- one for your pocket and another for your briefcase.

Charge capacity: There is a huge range of available charging capacities -- that is, how much energy each charger can store at once. Capacity is measured in milliamps per hour (mAh), and models can range from around 3,000 mAh (enough to double the battery life of your smartphone) to more than 20,000 mAh, which is ideal for laptops.

Charge speed: Nobody likes to wait, and some charger manufacturers capitalize on this by emphasizing charging speed in their designs. It’s common for chargers to be marketed based on how quickly they can charge common devices, so look for this detail if speed is important to you.

Connections and cords: Virtually all portable chargers have a USB port, but some may support several types of connections and come equipped with a variety of cords.

Special features: While many chargers just stick to Job #1, others may have features like built-in flashlights or emergency alarms.

Durability: Portable chargers are particularly popular among those who like to go off the beaten path while remaining connected. That’s why some manufacturers make their chargers waterproof, shatterproof and otherwise tough as nails.

Price: When price is an object, you’ll be able to find some chargers for as little as about $10. For the most durable chargers with the highest capacities, prices can exceed $100.

When you need a recharge on the fly, portable chargers are clearly the way to go. But if you ever have trouble getting a charge in your own home, don’t hesitate to reach out to your professional local electricians!

The electricity you use to power your home is most likely generated by burning coal, with some nuclear and natural gas-fueled current in the mix for good measure. However, that could all be changing, and faster than anyone expected. While renewable fuel sources like solar and wind power make up only a small part of the nation's electrical grid today, wind could actually be the leading source of electricity in little more than three decades.

Viable and Competitive

Wind could surpass other sources and provide as much as a third of the United States’ electricity by 2050, according to a report by the U.S. Department of Energy (DOE) Wind and Water Power Technologies office. Wind currently weighs in at only 4.5 percent of the supply, but if projections hold, that will increase to 10 percent by 2020 and 20 percent by 2030.

“The wind industry can be characterized by the substantial growth of domestic manufacturing and the level of wind deployment seen in recent years,” José Zayas, director of the DOE Wind and Water Power Technologies office, said to EcoWatch. “Wind power systems are now seen as a viable and competitive source of electricity across the nation. Wind power’s emerging role is an important option in a portfolio of new energy solutions for future generations.”

Benefits to Public Health, Environment

Should the prediction of wind's dominance come to pass, it would have numerous benefits for the environment and for consumers. Even at current levels, wind has reduced water consumption by 36.5 billion gallons and carbon emissions by 115,000,000 metric tons compared to traditional power sources, according to the government.

That means a lot less carbon getting released into the atmosphere, helping to slow our contribution to climate change. Plus, once the infrastructure is built, wind is free to harvest, and doesn't have the same environmental tradeoffs as coal and natural gas. The benefits “can address key societal challenges such as climate change, air quality and public health, and water scarcity,” the report said.

Uncertainties Looming

The rosy projection is just that. There are numerous uncertainties that could affect how well wind power actually does in the future, including government policies to incentivize wind or decentivize coal usage, the supply and price of natural gas, and the demand for electricity overall in the United States.

The technology around wind generation will have to hold its own as well. Growth in market share depends on continued advances in efficiency, more transmission capacity and better weather forecasting so we can best take advantage of favorable gusts.

Global Optimism

Should the growth of wind continue as predicted, there could be hope for a cleaner, healthier future. And what's good for the United States can be good for the rest of the world as well.

“The global energy market of the future is poised to be the largest market the world has ever known,” Secretary of State John Kerry said in a speech about wind power. “Pursuing cleaner, more efficient energy is actually the only way that nations around the world can build the kind of economies that are going to thrive for decades to come.

The relationship between weather and energy usage is a never-ending cycle. Spikes and drops in temperature and humidity lead to spikes and drops in energy use (and costs), which in turn correspond with spikes and drops in greenhouse gas emissions, further affecting climate. What does this relationship mean when it comes to your energy usage?

Temperatures above 100 and below 40 stress your heating and cooling system, pushing it to capacity, reducing efficiency, and draining energy supplies, along with your wallet. Quite simply, this amounts to less bang for your buck in terms of comfort. Add to temperature issues, wind, cloud cover, and precipitation and the snowball effect continues, further impacting comfort levels, not to mention your ability to illuminate interior spaces. Compound the issues – and the population affected – and you’ve got grid strain to boot.

That depends on the source of energy. In the US, 83 percent of energy usage comes from fossil fuels, which release gases such as CO2 into the environment during the creation of energy. Unfortunately, these gases trap heat in the atmosphere. Atmospheric greenhouse gases have increased 30 percent since the pre-Industrial Revolution era alone, and the level continues to rise with energy demand. As levels increase, so does the effect on the environment. Thousands of scientists agree the trapped gases are currently affecting the climate, and will increasingly weigh on it as time goes on. This has resulted in an increase in interest in cleaner forms of energy, including nuclear, solar, wind, and geothermal.
