Example: Solar, geothermal and wind energy plants are enormously expensive to build and maintain compared to traditional coal and gas fired power plants.
2. ‘Alternative energy’ tends to create its own resource utilization and environmental problems.
Example: Producing ethanol fuel from corn reduces the available food supply as well as the amount of arable land.
Example: Wind turbines kill endangered hawk species.
Example: Hydroelectric power (dams) destroy natural river systems and make land unusable.
Tired of the after-lunch energy crash? Stay away from fast food and opt for a salad with chicken, tuna or other protein instead.
Of course, many factors contribute to your level of energy but one of the most influential is what kinds of food you put in your body. Overall, a healthy diet with fresh, minimally processed foods will give you drastically more energy than a diet of mostly processed food.
Specifically, adding the following eight foods to your diet will rev up your energy and help keep you from yawning at 10 a.m., feeling your eyelids get heavy at 1 p.m., and nodding off during your afternoon meeting at 4 p.m.–and they taste great too. (NOTE: Eating the certified organic versions of these foods will increase their energy-boosting power even more.)
1. Lean Beef or Chicken (ideally free-ranged)
Adding a little protein to every meal is essential to keep your organs functioning and your energy levels up. Lean protein also contains tyrosine, an amino acid that helps your brain produce the chemicals norepinephrine and dopamine, which improve your mental function. Turkey, pork tenderloin, eggs, shellfish and sardines also contain tyrosine.
2. Black Beans
Complex carbohydrates like those in black beans and other legumes help keep your blood sugar levels balanced throughout the day, providing a steady, slow-burning source of energy to make you feel awake. Plus, black beans are a rich source of iron, an integral part of hemoglobin, which transports oxygen in the body, and key enzyme systems for energy production and metabolism.
Seaweeds like kelp, wakame, arame and dulse can be found in Asian grocery stores and health food stores. It can be eaten dried, straight out of the bag, or added to soups, salads and vegetables. Seaweed contains the broadest range of minerals of any food–the same minerals found in the ocean and in human blood. It also contains pantothenic acid and riboflavin–two B-vitamins needed for your body to produce energy.
Keep a glass of water handy all day long; staying hydrated is key to keeping energy levels up.
These tasty nuts are rich in manganese and copper, both of which are essential cofactors of an enzyme called superoxide dismutase. This enzyme helps keep energy flowing by inhibiting free radicals inside cells’ mitochondria (the energy-producing area of cells). Plus, they also contain riboflavin, another important component of energy production.
We know, it’s not really a food, but it’s so important that we decided to include it anyway. Water is necessary for your body to produce energy, including digesting, absorbing and transporting nutrients. If you don’t drink enough of it, your cells will be less able to receive the nutrients they need for energy, leaving you feeling sluggish. If plain water doesn’t appeal to you, try spicing it up with a squeeze of lemon, lime or other citrus.
This melon is an exceptional energy food because of its combination of vitamin B6, dietary fiber, folate, and niacin (vitamin B3). The B vitamins (necessary for the body to process sugars and carbs) combined with fiber (which helps the sugars be distributed gradually) support energy production by keeping blood sugar levels stable.
This tiny fruit often gets overlooked in favor of the more common apple or orange, but it packs a powerful punch. With more vitamin C than an equal amount of orange, it’s a potent energy-boosting food. When vitamin C levels are depleted, people often feel tired. One study found that women with low vitamin C levels felt more energized after receiving vitamin C daily. “They felt better and they had more energy,” said Carol Johnston, PhD, assistant professor of food and nutrition in the family resources department at Arizona State University. Other foods rich in vitamin C include raw red or green pepper, broccoli, strawberries and Brussels sprouts.
This morning favorite is loaded with soluble fiber, a key to slowing down carbohydrate absorption and keeping blood sugar levels steady. “A fiber-packed whole grain cereal, oatmeal is your best breakfast choice for long-lasting energy,” says William Evans, PhD, director of the nutrition, metabolism, and exercise laboratory at the University of Arkansas for Medical Sciences/Veterans Affairs Medical Center.

For apparently the first time ever, during the first quarter of 2014, electricity generated by non-hydro renewables (i.e., biomass, geothermal, solar, wind) exceeded that provided by conventional hydropower. This is according to data in the latest issue of the U.S. Energy Information Administration’s (EIA) “Electric Power Monthly,” with preliminary data through to March 31, 2014.Reblogged 3 hours ago from www.renewableenergyworld.com
The electric company in Ontario is called HydroOne (formally Ontario hydro)
It means that you pay your own power bill.
The water bill needs to be in the property owners name, it is unlikely you will ever have to pay it while renting.
If possibly find an inclusive apartment. If you are paying hydro pay attention to things like the age of the appliances, older fridges and stoves daw much more power than newer and can add $30 to your power bill monthly. Also an important one is heating and cooling. Basement apartments are notorious in Toronto for electric heating due to heavy municipal code placed upon the nature of enclosure as well as ventilation of a gas furnace.
Electric heat in the winter can add literally a hundred or two dollars depending upon the size to your unit. Air conditioning in the summer can also add a pile of money.
Look for something inclusive if possibly, it is usually well worth the extra $50/mo.
If you cannot take note of the appliances, heating and colling. Also have the landlord point out your meter (if only to ensure that the number of meters matches the number of units)
It really depends on how energy efficient and insulated the home is for me to be able to tell you how much the BC Hydro bill will be. My client’s 1000 SF 2 bedroom, 1 bath home unit $35/month. But one of our other client’s 600 SF 1 bedroom, 1 bath unit costs $65/month. Obviously it depends on your home’s heating source and also if you have double glazed windows, good insulation, etc.
Sorry I couldn’t be more helpful. You can always ask the landlord how much the previous tenant’s hydro bill was, or ask someone in the neighboring 1 bedroom apartment.

I'm doing a chem report on biofuels and ethanol and can't find a list of cars that run on it. Any help would be fantastic and musch appreciated.
All modern gasoline cars are required by law to tolerate up to 15% ethanol content, the computer chip adjusts the fuel air ratio accordingly. Premium gasoline is E10 (10% ethanol), the legislation to call E10 premium unleaded was put in place because people wasn't buying it when labeled as gasohol.
Many car computer chips are programmed to handle up to 30% ethanol just to be on the safe side and you can buy post processors which increase the gain on the control signals in order to allow operations up to 100% ethanol provided that the fuel injection jets have the capacity required. Only one of those "conversion kits" have been approved by the EPA but that's mostly due to the complicated approval process rather than the technology.
All diesel cars can operate on biodiesel, provided that it's actually been made properly (transesterification) and isn't just vegetable oil poured into the tank. Unprocessed vegetable oil would work but would irreparably gunk up the engine.
All gasoline engines can run on bio-butanol without modifications.
All Fischer Tropsch biomass to liquid fuels are essentially designer fuels and can be better for the respective cars than fossil sourced gasoline and diesel ie.: FT synthesized gasoline is just a more pure gasoline and FT synthesized diesel is just a more pure diesel (you actually need to add a little sulfur or biodiesel to synthetic diesel in order to provide some lubrication as it's too pure).
Whether any fuel is good or bad for the environment has more to do with from what and how that fuel is produced than what that fuel is. One gallon of corn ethanol takes the energy equivalent of 0.8 gallons of gasoline and ethanol only contains 2/3 the energy by volume of gasoline so it's like burning 1.2 gallons of gasoline to get 1 gallon of gasoline's worth of energy so corn ethanol is worse for the environment than gasoline whereas one gallon sugar cane ethanol only takes the energy equivalent of 1/8 a gallon of gasoline to produce so burning sugar cane ethanol is better for the environment than burning gasoline. Likewise, Fischer Tropsch synthetic fuels made from coal or natural gas actually doubles the release of greenhouse gases but if they're made from biomass gasification then it's actually carbon negative ie.: a net removal of CO2 from the atmosphere. Hydrogen is currently made from steam reformation of natural gas so burning hydrogen is bad for the environment, it takes more energy to make it by electrolysis and that energy would be from coal power plants so hydrogen by electrolysis is even worse for the environment.
The oil companies are mixing high sulfur diesel with Fischer Tropsch synthetic diesel made from natural gas or coal in order to meet new federal low sulfur requirements.
Well first it has to be made from biological sources, usually the fermentation of sugars and starches from plants. If the ethanol is made from high temperature Fischer Tropsch from the gasification of natural gas, coal or heavy oils then it's still a fossil fuel, if it's from the gasification of biomass then it's a bio fuel. Of course the equipment needed for synthesis of ethanol or methanol is the same equipment needed for synthesis of gasoline and diesel and is expensive so most ethanol is made by biological processes like fermentation. Note that fermentation takes energy, particularly from starches which have to be first broken down into sugars and if the energy is from fossil sources then even ethanol from biological sources would still be fossil fuel. Specifically, to produce one gallon of corn ethanol, it takes the energy equivalent of 0.8 gallons of gasoline and corn ethanol only has 2/3 the energy of the same volume of gasoline so with corn ethanol, you're burning the equivalent of 1.2 gallons of gasoline in fossil fuel to get a 1 gallon of gasoline equivalent energy in ethanol.
To use ethanol, you use it in a gasoline engine with the fuel air ratio adjusted to account for the lower energy density, ie.: increase the rate that the fuel is injected into the engine. The difference between a regular modern car and a flex fuel car is that the computer chip on the flex fuel car is programmed to allow for gasoline that's up to 85% ethanol (probably programmed for up to 95% to be on the safe side) whereas the regular car would only be programmed for up to 15% ethanol (probably up to 35% to be on the safe side), likewise the fuel injectors are sized appropriately and the fuel lines, fuel filter, seals and fittings on the flex fuel cars would be more resistant to ethanol. The fuel filter needs to be larger cause every time you go from using mostly gasoline to using mostly ethanol, some varnish and debris from the gasoline gets loosened up and can clog the fuel filter.
What is biofuel, ethanol, droughts, and high price of what? And How is it effecting the food crisis?
Biofuel is any fuel that is made from biomass, which include bio-diesel, corn ethanol, cellulosic ethanol, etc.
The current debate is that food prices are being pushed up because part of the supply, in particular, corn, is being diverted to make ethanol. There are some truths to this.
The solution is to use "non-food" biomass, like wood, or straw, or agricultural wastes like corn stalk, etc. To produce biofuel. There are many companies that are trying to do this, but so far, none of them have achieved large commercial production yet. This is because it is a lot easier to make ethanol out of sugar or starch than out of cellulosic materials.
The real shame in this is the impact on the poor countries. These people already have so little of disposal income that price increases in staples like rice or wheat mean they will have to eat less. A sad situation for a world that is so full of technical wonders and relative abundances.

Oh, Gwyneth Paltrow.
The actress, who recently compared reading mean things about herself on the Internet to being as dehumanizing an experience as war, is raising eyebrows yet again.
In her most recent Goop newsletter (no. 16!), Paltrow relays that she’s just “fascinated” by the power of the human consciousness — like the effect words can have on water, for example, or more crudely put, that water might have feelings.
I am fascinated by the growing science behind the energy of consciousness and its effects on matter. I have long had Dr. Emoto’s coffee table book on how negativity changes the structure of water, how the molecules behave differently depending on the words or music being expressed around it. Below, Dr. Sadeghi explores further.
With Paltrow’s reputation as one of the most unrelatable celebrities, this new batch of Goop sounds right up her alley.
Keeping Paltrow’s latest statement in mind, we’d like to leave you with a few words recently spoken by Mindy Kaling at Harvard Law School’s Class Day:
“In Hollywood, we all think we’re these wise advice givers, and most of us have no education whatsoever. Actresses can become nutritionistx, experts in baby care and environmental policy. Actors can become governors, pundits, or even high-ranking officials in religions made up a mere 60 years ago.”Reblogged 13 hours ago from www.huffingtonpost.com
CHOWCHILLA, Calif. (AP) — The scarcity of irrigation water in drought-stricken California has created such a demand for well drilling services that Central Valley farmer Bob Smittcamp is taking matters into his own hands.
He’s buying a drilling rig for $1 million to make certain he has enough water this summer for thousands of acres of fruit and vegetable crops.
“It’s like an insurance policy,” said Smittcamp, who knows two other farmers doing the same thing. “You have to do something to protect your investment.”
With California in a third dry year, well drilling is booming across the nation’s most productive agricultural region, and some drilling companies are booked for months or a year. In some counties, requests for permits to dig new wells have soared, more than doubling over this time last year.
Farmers expect to get only a fraction — if any — of the water they need from vast government-controlled systems of canals and reservoirs interlacing the state. In an effort to make up the difference, they are drilling hundreds of feet deep to tap underground water supplies.
Smittcamp said a licensed driller he often hires approached him, saying the demand for drillers is so high that Smittcamp needs his own full-scale drilling rig.
Smittcamp, whose Wawona Packing Co. farms thousands of acres, said he has written a $150,000 check as a deposit and the rest is due upon delivery of the $1 million rig, which he expects to happen soon.
He estimates that he spends $4,000 an acre tending his peach and grape crops before the harvest. If a well were to run dry mid-season with nobody to call, Smittcamp said he could lose that investment — and perhaps entire orchards or vineyards.
When the rig isn’t being used on Smittcamp’s land, he said the driller will put it to work on neighboring farms to recoup the investment.
The boom driving farmers to such lengths is a result of drought and a steadily improving economy, said John Hofer, an underground water consultant and executive director of the California Groundwater Association. Hofer said his consulting firm started receiving more calls last year, and that’s when he predicted the rising demand for drillers would follow.
“I kept telling my friends and associates to look out, that it was going to get crazy, and it has,” he said. “Drilling is up big-time.”
The figures prove it. In Fresno County, which leads the nation in agricultural production, officials issued 256 permits to dig new wells in the first three months of 2014, more than twice the number compared to the same time last year. That includes all types of water wells used for agriculture and homes.
In Tulare County, the number of permits issued to dig farm wells alone has tripled to 245. In Kern County, farmers took out 63 new well permits in the first quarter of the year, more than quadrupling last year’s number.
The price to dig a well depends on the depth and ground composition, drillers say, costing a farmer anywhere from $50,000 to $500,000 before installing the pumps.
Tapping groundwater has other costs. The water that was deposited underground naturally over thousands of years isn’t being replaced as rapidly as it’s being drawn, causing the ground in the Central Valley to sink in a process called subsidence. In California, there is little if any regulation of groundwater pumping by the state.
In most years, Central Valley farmers draw one-third of their water from wells, while the remaining two-thirds comes from California’s State Water Project and the federal Central Valley Project. Most farmers expect to receive no water from either this summer, and that ratio is dramatically shifting to underground water supplies, which could eventually run dry.
Matt Rottman, president of Rottman Drilling Co. based in Lancaster, said his mid-sized firm of three rigs is backlogged 15 months. For a recent job near Bakersfield, his crew dug a 1,840-foot well. Three wells coming up later this year in the Central Valley will hit depths of 2,000 feet.
Farmers calling Rottman tell him they’re in a pinch. They don’t expect any water from the state and federal water projects this summer, and Rottman said the market price of buying irrigation water elsewhere has shot up three or four times.
“They’re shut off,” he said. “They’ll be looking at crop damage if they don’t get wells in.”
Mike Maggiora, owner of Gillroy-based Maggiora Bros. Drilling Inc. and president of the California Groundwater Association, said he suspects that some drillers are backlogged because farmers are calling several firms to see who responds first. He’s booked for the next three months.
His eight crews work 24 hours a day for weeks drilling each well, which Maggiora said is a nice change from two years ago when the economy was bad and work was hard to find.
Now, Maggiora said he has trouble finding workers willing to put in the grueling hours. He also fears today’s boom will cause a run on supplies, such as the steel casings used to keep the walls from caving in. So he’s ordering them by the truckload.
Smittcamp said he worries that so much drilling could cause underground water supplies to run dry in little more than a decade. He blames politicians for failing to give farmers any other options, leaving them to fend for themselves.
This summer, Smittcamp said he has to come up with two-thirds of his water that would normally come from the state and federal water deliveries.
“This year, we get none out of the projects,” he said. “So we’ve got to pump the whole enchilada.”Reblogged 18 hours ago from www.huffingtonpost.com
