Technologies of Old Some renewable energy technology and conventional fossil fuel energy sources like coal-powered electricity production are more than a hundred years old. Does that make it old technology? The technologies of coal power continued improving over the century. Today’s electricity production plants are more efficient, safer and more streamlined than the earlier versions. Renewable energy technology options like wind power and hydropower have been around for a long time. They pre-date some of the conventional sources of electrical power

What is solar fuel? Solar is about the Sun. Solar fuel diminishing can’t be about the sun running out of energy; that is unlikely, and not something we can control. It will be an eternity before the matter needs urgent adaption strategies. Climate change is a more pressing issue. Maybe for climate change, we can focus on renewable energy options and solve the issues with them. The plants and the ground absorb and store the sun’s energy. Plants are biomass as

You need to charge a car battery If your battery is too flat to start your car you can solar charge a car battery. When you charge a car battery with solar panels it’s best to connect the charger directly to the battery. A normal plug-in battery trickle charger does the same thing. It is easy to attach the solar panels and the charger to the battery. The chargers come supplied with alligator clips or attaching clamps. Can you charge with

Hydroelectric power and no pollution Water is a means for storage of renewable energy Water moving through and rotating a turbine creates hydroelectric power. The amount of power output is dependant on the size of the turbine and its turning speed. The faster the turbine moves the greater the power that will be generated. Also, the longer period over which the turbine operates the greater the electricity produced. The power extracted by the turbine impellers relies on the available kinetic

Is energy complicated if renewable? I am sure energy is essential but is energy complicated, or easy? The first complication of many energy systems, including renewable energy power options, have to do with funding. The upfront capital cost in any generation system is high. There must be an investment in the energy facility before electrical power is available. You’ll either need to invest in increased capacity, reduce energy usage so the existing output remains adequate, or tolerate interruptions. Issues like

Green power from renewables Solar power and wind turbine applications are both in the residential context. How favourable are residential renewables? We will look generally and then at the residential application. Solar photovoltaic (PV) panels and wind power turbines generate electricity from renewable sources of energy.  IRENA statistics indicate and compare the international output and price for renewables like solar, wind and hydropower. The IRENA reports indicate that after hydropower, wind power and then solar power are the most cost-effective

Can’t access solar panels for renewable energy? Many state utilities buy green energy from homeowners with solar panels. The utility buys green power via a feed-in tariff that it pays for electricity panel owners to share with the grid. The sale of the excess capacity from existing installed solar systems is renewable electricity from solar PV. When there is excess generated electricity selling it lowers the electricity bill of the seller. The purchaser has access to clean renewable energy. Another

What are the downsides of solar power? One of the downsides of solar power it’s an intermittent renewable energy source. Intermittent provisions will have disadvantages. That solar power downside comes because the earth spins on an elliptical axis around the sun. That means sunlight is available for about half of the day. Sunlight varies consistently across the globe’s surface and during seasons of the year. People who enquire about solar power generation mention the high capital cost to purchase and

Re-discovering 19th-century technology for clean fuel economy  Can some of the 19th-century energy and fuel technologies be resurgent? In considering the coming clean fuel economy let’s examine what the situation was like back then. Before the 18th century, most works used manual labour: That meant the muscular energy of animals, people and biomass sources. Biomass (mainly firewood) provided energy for heating and cooking. Other sources of natural energy, such as windmills and watermills, contributed to very specific works like milling

Solar energy is the future Do you think “solar energy is the future”, really? One needs to consider how long fossil fuels are going to be economically available. If you are considering renewables like solar energy, the future may lie in innovation in battery storage. Better batteries would make renewable energy more sustainable and attractive. Solar power comes from photovoltaic (PV) panels. In 1873 the photovoltaic effect was first demonstrated. It took until 1954 to make it work effectively. To
