Renewable Energy Options
4
Solar energy efficiency in the UK: Portishead
5
Portishead is an ideal location for solar PV
6
Why so much better? High UV Low pollution levels Cooler summers Performance as good as Spain owing to temperature Because of significant drop-off above 30°C Only one day a year in Portishead!
7
Portishead is also ideal for: Wind Wave Tide
8
Examples of investment in renewables...
9
Island of Eigg
11
Flatholme
13
Both these concentrate on wind and sun Simple to install Island location; delivery a challenge Many more options on mainland...
14
Primary challenge with renewables: Free energy after installation Significant up-front cost Government incentives to help with this: Feed-in Tariff for PV Paid for ALL the electricity you generate And you benefit from free electricity From April 2014 – Renewable Heat Incentive (RHI) Paid for offsetting fossil fuels with renewables Typical pay-back of 5-7 years Ongoing savings from reduced energy bills
15
Examples of renewables: Biomass (pellet) boilers Suitable for older properties with average insulation Heat pumps Suitable for modern, well insulated properties Solar thermal for hot water Commercial BiomassDomestic Biomass
16
Further challenge: Mains gas From 2016 no new houses will be connected to the gas main Mandatory requirements: Super-efficient homes Renewable energy sources
17
The future: PV is simple and inexpensive to install Efficient and maintenance free Solarsense panels – low ‘carbon footprint’ Manufactured in Sweden using hydroelectricity Discreet PV systems available...
18
Solar Tiles Solar Slates
19
Complete solar roofs HighgroveCroyde Holiday Cottage
20
The future: Low energy lighting Battery storage – for electricity at night Heat pumps Extract energy from air or ground 1kW of electricity produces 3kW heat Electric vehicles When do you have time to charge a car? Most cars stand idle for 80% of the day Kendleston Manor
21
Community: “Power Parks” Sun or wind Typical investment of £250 to £5,000 Guaranteed return of 5-8% for 20 years Biomass Area heating schemes Blocks of flats or entire streets
22
The case for microgen: Electricity generated where it’s needed... 35% outOnly 1% out!
