Should cogeneration be considered a green energy technology?

Posted by Alex Barrett on 22 June 2017 at 3:01 pm

Should cogeneration be considered a green energy technology?

We consume energy in two main ways, as electricity and as heat. These are produced, distributed and used in very different ways. Most electricity is generated by centralised power stations, with a relatively small fraction being produced at the point of use. It is then distributed, potentially ov…

Why buy a hybrid inverter for your solar PV system?

Posted by Aderanti Kudehinbu on 21 June 2017 at 9:45 am

Why buy a hybrid inverter for your solar PV system?

The initial cost of a hybrid inverter is quite high, but this is offset by the ability to use your generated power more flexibly, rather than having to buy energy from the grid when the solar panel isn’t generating. Hybrid inverters have proven reliability across various grid types. Modern …

Condensation and ventilation: preventing damp in your home

Ventilation is a surprisingly important element in keeping your heating bills down. How? Because a home that can’t “breathe” is one which traps moisture on the inside and causes damp. Even if a home has high levels of insulation, a damp wall can lose up to 40% more heat than a d…

Greener than most by leaving a lighter footprint

Have you ever considered the carbon footprint of a funeral? You may be thinking this is a bit of morbid topic for a YouGen blog, but believe it or not 0.2% of global greenhouse gas emissions are due to a variety of modern day funeral methods. Although the environmental impact is likely to be the …

How do you assess the efficiency of a ground source heat pump?

Posted by Alex Barrett on 13 June 2017 at 10:57 am

How do you assess the efficiency of a ground source heat pump?

Ground Source Heat Pumps (GSHP) extract heat from the ground, and use it to produce hot water. The temperature in the subsurface remains around 11-12oC throughout the year [1]. By burying pipes just a few metres below the ground you can take advantage of this readily available supply of thermal e…

Solar Chimneys: Passive solar ventilation and electricity generation.

Posted by Alex Barrett on 7 June 2017 at 3:15 pm

Solar Chimneys: Passive solar ventilation and electricity generation.

The solar chimney is designed to harness the fact that hot air rises, providing passive ventilation for a building. A solar chimney can be used to cool a house during warm weather, and generate heat during cold times of the year. There have also been efforts to build industrial scale solar chimne…

What are the financial pros and cons of a biomass boiler?

The environmental case for biomass is unquestionable - we can grow more of it, unlike oil, gas and liquefied petroleum gas (LPG). But what about the cost of a biomass boiler? The price of installation, fuel and maintenance are important considerations when choosing a new boiler. In this v…

Are Infrared panel heaters a good way to heat a room?

Infrared panel heaters are a relatively new way to heat your house. They work very differently to radiators, and have some advantages when it comes to energy efficiency. Infrared panel heaters use radiation to heat the room instead of convection. This means that they deliver heat directly to …

How green is Hydroelectricity?

Large hydropower schemes account for the majority of the world’s renewable energy supply. Unlike wind and solar, hydroelectricity can provide a constant stream of renewable power, regardless of the weather or the time of year. Hydroelectric dams can be used to store power, and can quickly b…

Is it true that people in passive houses roast in summer?

Passive House is a voluntary energy performance standard that results in buildings that are extremely airtight and have good levels of insulation. In such buildings, little energy is required for space heating and cooling so you can do away with conventional heating systems. But this begs the que…

Are sunnier days always the best for solar PV generation?

People often remark that solar panels do not need a sunny day to generate. Turns out a cloudy day can sometimes generate more than a sunny one. Three years ago, JoJu Solar installed a 10kW flat roof system on Artsadmin in Central London. It was the first project with panels facing East and We…

How important is solar shading to passive solar building design?

Trying to get indoor spaces to be the right temperature is a constant struggle. During cold parts of the year we use large amounts of energy for heating, but when warm weather arrives we suddenly want to cool down our buildings, either with fans or air conditioning. There seem to be relatively fe…
