It's possible April of 2019 will prove to be an historic month for renewable energy.For centuries, coal has been one of the primary sources of energy in the United States. But in recent years, energy sources such as wind, solar and hydro have been catching up.Bruce Bohannan is hoping his home will eventually be carbon neutral, which means it'd solely be powered by renewable energy. It's a process he started 10 years ago when he invested in solar panels. Bohannan’s house is not your average American house."You can see a little bit at the very top of the house, that was our first phase of solar panels," Bohannan said."I have a daughter who will outlive me into the world of the future, and I really put them on for my daughter's future... for her climate future," Bohannan added.A decade later, Bohannan is witnessing a change he had always hoped for to lower carbon emissions.In April -- for the first time in U.S. history -- forecasters say renewable energy sources generated more electricity than coal."It's an indicator of what's to come," Dennis Wamsted, an energy analyst for the Institute for Energy Economics and Financial Analysis, said.His claim is based on a short-term forecast of data for the month of April. Date from the U.S. Energy Information Administration shows renewable energy surpassing coal production. "The coal industry 10 years ago generated about 50 percent of the nation's electricity. And in the past 10 years that percentage has dropped from 50 percent to this year, EIA [Energy Information Administration] is saying about 24 percent," Wamsted said.Electricity generation can be broken into four main categories: Natural gas generates 35 percent of our electricity; coal generates 24 percent; nuclear power 20 percent; and renewable sources generate 18 percent (3 percent is other). The percentage for coal is predicted to decrease in the coming years, whereas renewable energy is expected to do the opposite. Wamsted predicts renewable energy will surpass coal for good in three years.“Coal's costs are going up, and renewable costs are going down which gives me a great deal of confidence that this transition is going to continue into the future," Wamsted said.So what happened in April that spiked renewable energy production? Wamsted says, think about the changing seasons.April is a big month for snow melt which powers hydroelectricity. In many places, there's often more wind in the springtime to power wind turbines. And solar energy increases in the spring with more direct daylight in the United States.The coal industry's production also plays a role. Many plants shut down for maintenance in the spring, since most people around the country aren't cranking up heat or the A.C.While this data signals a big milestone for renewables, it's not a total surprise. Clean energy is now cheaper than coal because technology has improved, and manufacturers are more efficient.Energy Program Director Rob Sargent with Environment America says the coal industry, on the other hand, is facing a grim future.“It's been declining steadily, and uh, coal plants are shutting down left and right. Nobody is building new ones," Sargent said.The possible end of the coal industry has many concerned for their livelihood, but there is hope for the American workforce.A report done by nonpartisan business group 'Environmental Entrepreneurs' shows nearly every U.S. state saw an increase in clean energy jobs last year. In fact, jobs involving renewable energy outnumbered fossil fuel jobs three to one, and employers expect job growth to continue. "There is no question that right now in America there are more jobs in the clean energy industry than there are in the fossil fuel industry," Sargent said.Change can be challenging, but Sargent believes the increase in clean energy positions will ease the transition into renewables as a staple provider of energy. And clean energy proponents like Bohannan are convinced the change is only for the better."Anything we can do to leave carbon in the ground is the right answer for the earth. We need to drastically stop emitting carbon if we're going to have a positive effect on our climate chances over the next 50 years," Bohannan said.The United States is not the first nation in this energy transition. Renewable energy has already surpassed coal in the United Kingdom, and the country expects coal-fired energy generation will be completely cut off by 2025. 4450

In 2017, Uber unveiled a tip feature on its app to allow customers to leave their driver a tip. It turns out many customers do not leave a tip. According to a study conducted by Bharat Chandar, Uri Gneezy, John A. List, and Ian Muira with the University of Chicago, only about 16% of rides end with a tip. The study also found that 60% of Uber customers never tip, while 1% always leave a tip. List's study included 40 million trips in the cities of Chicago, Boston, San Francisco, Salt Lake City, Asheville, North Carolina, and Bloomington, Indiana.List's study found the average of those who do tip is .11, about 26% of their fare. The survey found that customers were more likely to tip between 3 to 5 a.m., as well as around 6 p.m. on Fridays; that female drivers, especially younger females, were more likely to earn tips; and that 5-star drivers were twice as likely to earn a tip as a 4.75-star driver.So should you tip? That is up to you, but know that according to the 992

In a speech from the Senate floor Thursday, Majority Leader Mitch McConnell (R-Kentucky) slammed the House's adoption of articles of impeachment as a "predetermined end" to a "partisan crusade," but did not give any specifics about the impending trial to be held in the Senate.McConnell's statement comes hours after the House of Representatives voted to impeach President Donald Trump in a vote that was largely along party lines. All but two Democrats voted in favor of the articles; no Republicans voted in favor.McConnell warned the impeachment risked "deeply damaging" institutions in the United States and claimed it could open the door for more partisan impeachments in the future."If the Senate blesses this historically low bar (of impeachment), we will invite the impeachment of every future president," McConnell said.Senate Minority Leader Chuck Schumer (D-New York), responded shortly thereafter, claiming McConnell failed to offer a defense for President Trump's actions in McConnell's 30-minute speech.Schumer also slammed Trump's decision to not participate in impeachment proceedings, and said Democrats would welcome the Trump administration to offer their own defense."Why is (McConnell) so afraid of relevant witnesses and documents?" Scumer said. "...can none of the president's men come defend him under oath?"McConnell also claimed that House Speaker Nancy Pelosi was "afraid" to send the articles of impeachment over to the Senate for a trial. Pelosi said Wednesday night that the House would delay sending the articles to the Senate until she could get assurances that the Senate would hold a fair trial.Last week, McConnell told news outlets that he is openly conferring with White House counsel on defenses for Trump. The comments sparked a call among Democrat lawmakers for McConnell to recuse himself during the Senate trial. 1866

In news that is both a little scary and gross, US Foods, an Alabama-based food distributor, has announced a voluntary recall of around 712 pounds of fresh and frozen raw beef and pork over the possibility that the products may be contaminated with human blood. It is suspected that an employee at the facility may have cut himself during the production of these items.While it can never hurt to check the food in your 430
