More Problems

Okay, so light pollution isn’t good. But perhaps you’re thinking, if we turn off the lights that illuminate our streets and sidewalks, homes and buildings, they’ll become dangerous. Car accidents are bound to increase on dark, busy streets, and walking on sidewalks out at night would be scary to say the least. Not to mention a poorly lit home is a target for sinister intruders.

So what do we do? Is there any sort of compromise?

New LED lighting offers some hope, but it’s certainly not all sunshine and rainbows.

From science fiction to massive solar plants in the American West, solar energy has fascinated and tantalized scientists and writers for generations.  The promise of easily-accessible, virtually free energy from the large fusion reactor at the center of our solar system (the sun) is enticing and we’re getting closer to harnessing its power effectively every day.

Solar power is interesting because it’s one of the few electrical energy systems that does not use a turbine to generate energy.  Photoelectric cells contain a material that releases electrons when hit by a photon, generating electrical power.  There are no moving parts, no fuel to burn and pay for, and only occasional maintenance to keep the system performing optimally.

So what is holding back the proliferation of solar energy?  Space and storage.  We can generate large quantities of energy from solar, but we do not, at present, have the right method to store that energy for periods without sunlight (night time and storms).  So far the best response has been homeowners installing solar cells on their own homes with battery storage systems linked into their own neighborhoods.  By splitting up generation and storage within the neighborhood itself, enough solar cells can be installed to generate energy both day and night.

Space is at a premium when it comes to energy generation.  Solar power plants take up more space than traditional plants, while generating less energy per square foot.  Because solar cells need to be placed over large areas to maximize sunlight, installing power plants in urban areas can be difficult.  Though installing solar cells on your home can be done simply.

We mentioned self-starting or “œblack-start” energy systems.  These systems can be started without power applied to the system, a huge benefit to fuel-fed power plants, and necessary in the event of major blackouts and power losses.  True, we can supplement with gas turbines or nearby power generation, but we also want black-start renewables.  Fortunately, hydroelectric power plants require no off-system power to function.

Hydroelectric plants are special because, while they also have a somewhat variable energy source, they also have one of the best energy storage systems available: potential energy.  Hydroelectric dams use flowing water to spin turbines, typically generated from lakes and rivers.  Rather than storing generated electricity, hydroelectric plants can store water at a higher altitude.  By storing water in special tanks, they have access to electrical generation potential by simply releasing the stored water and allowing it to spin the turbine.  Hydroelectric power is perfect for energy storage, but they’re limited to specific areas.

Power outages aren’t a very common occurrence in Australia and power supply in our country is quite steady at most times. Even when there is a power outage, it doesn’t last for too long. However, natural disasters such as bush fires, floods or storms can throw the power supply out of gear for a much longer duration; at times it may last for days or weeks.

When there is a power outage, you won’t be able to use any of the equipment or appliances in your home and you won’t be able to use the hot water system either. In fact, you won’t even be able to charge and use simple devices like your mobile phone, once the battery drains out. In short, it isn’t easy to manage many day-to-day activities without electricity. Here are some tips that will help ease the challenges you face during a power outage and deal with things in a slightly better way.

A power outage is something you should never take lightly. It’s always important to keep handy the contact details of a licensed and insured local electrician. The company should be able to provide prompt and reliable services when you need them. If you find that the power outage has impacted only your property, it’s best to call your electrician without delay.

Apart from checking if any circuit breakers have tripped, never try to tackle any electrical tasks on your own. For more information, simply speak with the experts at AllRound Electrical and take their advice on various aspects of electrical installations in your home. The number to call is – 1300 169 263.

Now encroaching into Post-Graduate territory, the 20+ year-old student has a more refined set of needs. Cool isn’t a requirement as much as function. The grad student is faced with the problem of desperately wanting to be a sophisticated adult, but is hindered by full schedules and mounting education costs. Be a hero by giving your favorite 20-something student a gift that acknowledges this new phase of their life:
